The MC74LVX373 is an advanced high speed CMOS octal latch with
3–state outputs. The inputs tolerate voltages up to 7V, allowing the
interface of 5V systems to 3V systems.
This 8–bit D–type latch is controlled by a latch enable input and an
output enable input. When the output enable input is high, the eight
outputs are in a high impedance state.
• High Speed: t
PD
= 5.8ns (Typ) at VCC = 3.3V
• Low Power Dissipation: I
CC
= 4µA (Max) at TA = 25°C
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Low Noise: V
OLP
= 0.8V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300mA
• ESD Performance: HBM > 2000V; Machine Model > 200V

1. 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 HIGH–to–LOW (t
OSHL
) or LOW–to–HIGH (t
OSLH
); parameter
