www.DataSheet4U.com RD74LVC16244B 16-bit Buffers / Line Drivers with 3-state Outputs REJ03D0527–0100 Rev.1.00 Mar. 14, 2005 Description The RD74LVC16244B has sixteen line drivers with three state outputs in a 48 pin package. This device is a non inverting buffer and has two active low enables (1G to 4G). Each enable independently controls four buffers. Low voltage and high-speed operation is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation. Features VCC = 1.65 V to 5.5 V All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VOUT (Max.) = 5.5 V (@VCC = 0 V or output off state) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C) High output current ±4 mA (@VCC = 1.65 V) ±8 mA (@VCC = 2.3 V) ±12 mA (@VCC = 2.7 V) ±24 mA (@VCC = 3.0 V to 5.5 V) Ordering Information Part Name RD74LVC16244BTEL Package Type TSSOP–48 pin Package Code (Previous Code) PTSP0048KA–A (TTP–48DBV) Package Abbreviation T Taping Abbreviation (Quantity) EL (1,000 pcs/reel) Function Table Inputs G H L L H: High level L: Low level X: Immaterial Z: High impedance A X H L Output Y Z H L Rev.1.00 Mar. 14, 2005 page 1 of 8 RD74LVC16244B Pin Arrangement 1G 1 1Y1 2 1Y2 3 GND 4 1Y3 5 1Y4 6 VCC 7 2Y1 8 2Y2 9 GND 10 2Y3 11 2Y4 12 3Y1 13 3Y2 14 GND 15 3Y3 16 3Y4 17 VCC 18 4Y1 19 4Y2 20 GND 21 4Y3 22 4Y4 23 4G 24 48 2G 47 1A1 46 ...
