MC74VHC126
Quad Bus Buffer
with 3–State Control Inputs
fabricated with silicon gate CMOS technology. It achieves
noninverting high speed operation similar to equivalent Bipolar
Schottky TTL while maintaining CMOS low power dissipation.
Low to place the output into high impedance.
output which provides high noise immunity and stable output. The
inputs tolerate voltages up to 7V, allowing the interface of 5V systems
to 3V systems.
April, 2000 – Rev. 1
The MC74VHC126 is a high speed CMOS quad bus buffer
The MC74VHC126 requires the 3–state control input (OE) to be set
The internal circuit is composed of three stages, including a buffer
