74VHCT245A
Octal Buffer/Line Driver with 3-STATE Outputs
Features
■ High Speed: tPD = 5.4ns (Typ.) at VCC = 5V
■ Power Down Protection on Inputs and Outputs
■ Low Power Dissipation: ICC = 4A (Max.) @ TA = 25°C
■ Pin and Function Compatible with 74HCT245
General Description
The VHCT245A is an advanced high speed CMOS octal
bus transceiver fabricated with silicon gate CMOS tech-
nology. It achieves high speed operation similar to equiv-
alent Bipolar Schottky TTL while maintaining the CMOS
low power dissipation. The VHCT245A is intended for
bidirectional
asynchronous
communication
between
data busses. The direction of data transmission is deter-
mined by the level of the T/R input. The enable input can
be used to disable the device so that the busses are
effectively isolated.
Protection circuits ensure that 0V to 7V can be applied to
the input and output(1) pins without regard to the supply
voltage. These circuits prevent device destruction due to
mismatched supply and input/output voltages. This
device can be used to interface 5V to 3V systems and
two supply systems such as battery back up.
Note:
1. Outputs in OFF-State
Ordering Information
Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the
ordering number. Pb-Free package per JEDED J-STD-020B.
