74VHC153
Dual 4-Input Multiplexer
device can be used to interface 5V to 3V systems and two
supply systems such as battery backup. This circuit pre-
vents device destruction due to mismatched supply and
input voltages.
General Description
The VHC153 is an advanced high-speed CMOS device
fabricated with silicon gate CMOS technology. It achieves
the high-speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power dissi-
pation. The VHC153 is a high-speed Dual 4-Input Multi-
plexer with common select inputs and individual enable
inputs for each section. It can select two lines of data from
four sources. The two buffered outputs present data in the
true (non-inverted) form. In addition to multiplexer opera-
tion, the VHC153 can act as a function generator and gen-
erate any two functions of three variables. An input
protection circuit insures that 0V to 7V can be applied to
the input pins without regard to the supply voltage. This
Features
■ High Speed: tPD = 5.0 ns at TA = 25°C
■ Low power dissipation: ICC = 4 µA (max) at TA = 25°C
■ High noise immunity: VNIH = VNIL = 28% VCC (min)
■ Power down protection is provided on all inputs
■ Pin and function compatible with 74HC153
