Octal Bus Buffer/Line Driver
Inverting with 3-State Outputs
The MC74VHCT240A is an advanced high speed CMOS octal bus buffer fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar
Schottky TTL while maintaining CMOS low power dissipation. The MC74VHCT240A is an inverting 3–state buffer, and has two active–low output enables. This device is designed to be used with 3–state memory address drivers, etc. The VHCT inputs are compatible with TTL levels. This device can be used as a level converter for interfacing 3.3V to 5.0V, because it has full 5V CMOS level output swings. The VHCT240A input and output (when disabled) structures provide protection when voltages between 0V and 5.5V are applied, regardless of the supply voltage. These input and output structures help prevent device destruction caused by supply voltage – input/output voltage mismatch, battery backup, hot insertion, etc. High Speed: tPD = 5.6ns (Typ) at VCC = 5V Low Power Dissipation: ICC = 4µA (Max) at TA = 25°C TTL–Compatible Inputs: VIL = 0.8V; VIH = 2.0V Power Down Protection Provided on Inputs and Outputs Balanced Propagation Delays Designed for 4.5V to 5.5V Operating Range Low Noise: VOLP = 1.1V (Max) Pin and Function Compatible with Other Standard Logic Families Latchup Performance Exceeds 300mA ESD Performance: HBM > 2000V; Machine Model > 200V Chip Complexity: 110 FETs or 27.5 Equivalent Gates ...
