74VHC125 Quad Buffer with 3-STATE Outputs
August 1993
Revised March 1999
74VHC125
Quad Buffer with 3-STATE Outputs
General Description
The VHC125 contains four independent non-inverting buff-
ers with 3-STATE outputs. It is an advanced high-speed
CMOS device fabricated with silicon gate CMOS technol-
ogy and achieves the high-speed operation similar to
equivalent Bipolar Schottky TTL while maintaining the
CMOS low power dissipation.
An input protection circuit insures that 0V to 7V can be
applied to the input pins without regard to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery backup. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
