Octal Bidirectional Transceiver with 3-STATE Outputs
General Description
The VHC245 is an advanced high speed CMOS octal bus
transceiver fabricated with silicon gate CMOS technology.
It achieves high speed operation similar to equivalent Bipo-
lar Schottky TTL while maintaining the CMOS low power
dissipation. The VHC245 is intended for bidirectional asyn-
chronous communication between data busses. The direc-
tion of data transmission is determined 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. All inputs
are equipped with protection circuits against static dis-
charge.
Ordering Code:
Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
Pb-Free package per JEDEC J-STD-020B.
