( DataSheet : www.DataSheet4U.com ) ® 74VHC126 QUAD BUS BUFFERS (3-STATE) PRELIMINARY DATA s s s s s s s s s s HIGH SPEED: tPD = 3.8 ns (TYP.) at VCC = 5V LOW POWER DISSIPATION: ICC = 4 µA (MAX.) at TA = 25 oC HIGH NOISE IMMUNITY: VNIH = VNIL = 28% VCC (MIN.) POWER DOWN PROTECTION ON INPUTS SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 8 mA (MIN) BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 5.5V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 126 IMPROVED LATCH-UP IMMUNITY LOW NOISE: VOLP = 0.8V (Max.) M (Micro Package) T (TSSOP Package) ORDER CODES : 74VHC126M 74VHC126T This device requires the 3-STATE control input G to be set low to place the output into the high impedance state. Power down protection is provided on all inputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage. DESCRIPTION The 74VHC126 is an advanced high-speed CMOS QUAD BUS BUFFERS fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.
