The MC74VHCT245A 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 two–way 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.
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 VHCT245A 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 = 4.9ns (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 = 1.6V (Max) Pin and Function Compatible with Other Standard Logic Families Latchup Performance Exceeds 300mA ESD Performance: HBM > 2000V; Machine Model > 200V Chip Complexity: 304 FETs or 76 Equivalent Gates
APPLICATION NOTES Do not force a signal on an I/O pin when it is an active output,
damage may occur. All floating (high impedance) input or I/O pins must be fixed by
means of pull up or pull down resistors or bus terminator ICs.
