MC74VHC373
Octal D−Type Latch
with 3−State Output
The MC74VHC373 is an advanced high speed CMOS octal latch
with 3−state output fabricated with silicon gate CMOS technology. It
achieves high speed operation similar to equivalent Bipolar Schottky
TTL while maintaining CMOS low power dissipation.
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.
The internal circuit is composed of three stages, including a buffer
output which provides high noise immunity and stable output. The
inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V
systems to 3.0 V systems.

SOIC Packages†
TSSOP Package†
This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high−impedance circuit. For proper operation, Vin and
Vout should be constrained to the
range GND (Vin or Vout) VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or V CC ).
Unused outputs must be left open.
Maximum ratings are those values beyond which device damage can occur. Maximum ratings
applied to the device are individual stress limit values (not normal operating conditions) and are
not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.

1. Parameter guaranteed by design. tOSLH = |tPLHm − tPLHn|, tOSHL = |tPHLm − tPHLn|.
2. CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load.
Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC / 8 (per latch). CPD is used to determine the
no−load dynamic power consumption; PD = CPD VCC2 fin + ICC VCC.
