ON Semiconductort The MC74VHC245 is an advanced high speed CMOS octal bus transceiver fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. It is intended for twoway asynchronous communication between data buses. The direction of data transmission is determined by the level of the DIR input. The output enable pin (OE) can be used to disable the device, so that the buses are effectively isolated. All inputs are equipped with protection circuits against static discharge. High Speed: tPD = 4.0ns (Typ) at VCC = 5V Low Power Dissipation: ICC = 4μA (Max) at TA = 25°C High Noise Immunity: VNIH = VNIL = 28% VCC Power Down Protection Provided on Inputs Balanced Propagation Delays Designed for 2V to 5.5V Operating Range Low Noise: VOLP = 1.2V (Max) Pin and Function Compatible with Other Standard Logic Families Latchup Performance Exceeds 300mA ESD Performance: HBM > 2000V; Machine Model > 200V Chip Complexity: 308 FETs or 77 Equivalent Gates Octal Bus Transceiver MC74VHC245 DW SUFFIX 20LEAD SOIC WIDE PACKAGE CASE 751D05 DT SUFFIX 20LEAD TSSOP PACKAGE CASE 948E02 M SUFFIX 20LEAD SOIC EIAJ PACKAGE CASE 96701 ORDERING INFORMATION MC74VHCXXXDW SOIC WIDE MC74VHCXXXDT TSSOP MC74VHCXXXM SOIC EIAJ w These devices are available in Pbfree package(s).
