MC74LCX14
Low Voltage CMOS
Hex Schmitt Inverter With 5
V-Tolerant Inputs
The MC74LCX14 is a high performance hex inverter with
SchmittTrigger inputs operating from a 2.3 to 3.6 V supply. High
impedance TTL compatible inputs significantly reduce current loading to
input drivers, while TTL compatible outputs offer improved switching
noise performance. A V
I
specification of 5.5 V allows MC74LCX14
inputs to be safely driven from 5 V devices.
Pin configuration and function are the same as the MC74LCX04, but
the inputs have hysteresis and, with its Schmitt trigger function, the
LCX14 can be used as a line receiver which will receive slow input
signals.
Designed for 2.3 V to 3.6 V V
CC
Operation
5 V Tolerant Inputs Interface Capability With 5 V TTL Logic
LVTTL Compatible
LVCMOS Compatible
24 mA Balanced Output Sink and Source Capability
Near Zero Static Supply Current (10
mA) Substantially Reduces
System Power Requirements
Latchup Performance Exceeds 500 mA
Current Drive Capability is 24 mA at Source/Sink
Pin and Function Compatible with Other Standard Logic Families
ESD Performance: HBM > 2000 V; Machine Model > 100 V

2. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device.
The specification applies to any outputs switching in the same direction, either HIGHtoLOW (t
