INTEGRATED CIRCUITS 74LVT16373A 3.3V LVT 16-bit transparent D-type latch (3-State) Product specification Supersedes data of 1994 Dec 15 IC23 Data Handbook 1998 Feb 19 Philips Semiconductors Philips Semiconductors Product specification 3.3V 16-bit transparent D-type latch (3-State) 74LVT16373A FEATURES • 16-bit transparent latch • 3-State buffers • Output capability: +64mA/-32mA • TTL input and output switching levels • Input and output interface capability to systems at 5V supply • Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs DESCRIPTION The 74LVT16373A is a high-performance BiCMOS product designed for VCC operation at 3.3V. This device is a 16-bit transparent D-type latch with non-inverting 3-State bus compatible outputs. The device can be used as two 8-bit latches or one 16-bit latch. When enable (E) input is High, the Q outputs follow the data (D) inputs. When enable is taken Low, the Q outputs are latched at the levels of the D inputs one setup time prior to the High-to-Low transition. • Live insertion/extraction permitted • Power-up reset • Power-up 3-State • No bus current loading when output is tied to 5V bus • Latch-up protection exceeds 500mA per JEDEC Std 17 • ESD protection exceeds 2000V per MIL STD 883 Method 3015 and 200V per Machine Model QUICK REFERENCE DATA SYMBOL tPLH tPHL CIN COUT ICCZ PARAMETER Propagation delay nDx to nQx Input capacitance Output capacitance Total supply current CL = 50pF; VCC = 3.3V VI = 0V or 3.0V Outputs disabled; VO = 0V or 3.0V Outputs disabled; VCC = 3.6V CONDITIONS Tamb = 25°C TYPICAL 1.9 3 9 70 UNIT ns pF pF µA ORDERING INFORMATION PACKAGES 48-Pin Plastic SSOP Type III 48-Pin Plastic TSSOP Type II TEMPERATURE RANGE –40°C to +85°C –40°C to +85°C OUTSIDE NORTH AMERICA 74LVT16373A DL 74LVT16373A DGG NORTH AMERICA VT16373A DL VT16373A DGG DWG NUMBER SOT370-1 SOT362-1 LOGIC SYMBOL 47 46 44 43 41 40 38 37 PIN DESCRIPTION PIN NUMBER 47, 46, 44, 43, 41, 40, 38, 37, 36, 35, 33, 32, 30, 29, 27, 26 SYMBOL 1D0 – 1D7 2D0 – 2D7 1Q0 – 1Q7 2Q0 – 2Q7 1OE, 2OE FUNCTION Data inputs Data outputs Output enable inputs (active-Low) Enable inputs (active-High) Ground (0V) Positive supply voltage 1D0 1D1 1D2 1D3 1D4 1D5 1D6 1D7 48 1 1LE 1OE 1Q0 1Q1 1Q2 1Q3 1Q4 1Q5 1Q6 1Q7 2, 3, 5, 6, 8, 9, 11, 12, 13, 14, 16, 17, 19, 20, 22, 23 1, 24 2 36 3 35 5 33 6 32 8 30 9 29 11 27 12 26 48, 25 4, 10, 15, 21, 28, 34, 39, 45 7, 18, 31, 42 1E, 2E GND VCC 2D0 2D21 2D2 2D3 2D4 2D5 2D6 2D7 25 24 2LE 2OE 2Q0 2Q1 2Q2 2Q3 2Q4 2Q5 2Q6 2Q7 13 14 16 17 19 20 22 23 SA00044 1998 Feb 19 2 853-1780 18989 Philips Semiconductors Product specification 3.3V 16-bit transparent D-type latch (3-State) 74LVT16373A LOGIC SYMBOL (IEEE/IEC) 1OE 1LE 2OE 2LE 1D1 1D2 1D3 1D4 1D5 1D6 1D7 1D8 2D1 2D2 2D3 2D4 2D5 2D6 2D7 2D8 1 48 24 25 47 46 44 43 41 40 38 37 36 35 33 32 30 29 27 26 4D 2∇ 1EN C3 2EN C4 1∇ 2 3 5 6 8 9 11 12 13 14 16 17 19 20 22 23 PIN CONFIGURATION 1OE 1Q0 1Q1 GND 1Q2 1Q1 1Q2 1Q3 1Q4 1Q5 1Q6 1Q7 1Q8 2Q1 2Q2 2Q3 2Q4 2Q5 2Q6 2Q7 2Q8 GND 1Q6 1Q7 2Q0 2Q1 GND 2Q2 2Q3 VCC 2Q4 2Q5 GND 2Q6 2Q7 2OE 1Q3 VCC 1Q4 1Q5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 1D3 VCC 1D4 1D5 GND 1D6 1D7 2D0 2D1 GND 2D2 2D3 VCC 2D4 2D5 GND 2D6 2D7 2LE 1 2 3 4 5 48 47 46 45 44 1LE 1D0 1D1 GND 1D2 3D SW00010 SA00043 LOGIC DIAGRAM nD0 nD1 nD2 nD3 nD4 nD5 nD6 nD7 D D D D D D D D E Q E Q E Q E Q E Q E Q E Q E Q nLE nOE nQ0 nQ1 nQ2 nQ3 nQ4 nQ5 nQ6 nQ7 SA00046 1998 Feb 19 3 Philips Semiconductors Product specification 3.3V 16-bit transparent D-type latch (3-State) 74LVT16373A FUNCTION TABLE INPUTS nOE L L L L L H H H = h = L = l = NC= X = Z = ↓ = nE H H ↓ ↓ L L H nDx L H l h X X nDx INTERNAL REGISTER L H L H NC NC nDx OUTPUTS OPERATING MODE nQ0 – nQ7 L H L H NC Z Z Enable and read register Latch and read register Hold Disable outputs High voltage level High voltage level one set-up time prior to the High-to-Low E transition Low voltage level Low voltage level one set-up time prior to the High-to-Low E transition No change Don’t care High impedance “off ” state High-to-Low E transition ABSOLUTE MAXIMUM RATINGS1, 2 SYMBOL VCC IIK VI IOK VOUT IOUT O Tstg PARAMETER DC supply voltage DC input diode current DC input voltage3 VO < 0 Output in Off or High state Output in Low state DC output current Output in High state Storage temperature range –64 –65 to +150 °C VI < 0 CONDITIONS RATING –0.5 to +4.6 –50 –0.5 to +7.0 –50 –0.5 to +7.0 128 mA UNIT V mA V mA V DC output diode current DC output voltage3 NOTES: 1.
