HD74LVC374A
Octal D-type Flip Flops with 3-state Outputs
REJ03D0355–0400Z
(Previous ADE-205-113B (Z))
Rev.4.00
Jul. 27, 2004
Description
The HD74 LVC374A has eight edge trigger D type flip flops with three state outputs in a 20 pin package. Data at the
D inputs meeting set up requirements are transferred to the Q outputs on positive going transitions of the clock input.
When the clock input goes low, data at the D inputs will be retained at the outputs until clock input returns high again.
When a high logic level is applied to the output control input, all outputs go to a high impedance state, regardless of
what signals are present at the other inputs and the state of the storage elements. Low voltage and high-speed operation
is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a
battery for long time operation.

VCC = 2.0 V to 5.5 V
All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V)
All outputs VOUT (Max.) = 5.5 V (@VCC = 0 V or output off state)
Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25 °C)
Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C)
High output current ±24 mA (@VCC = 3.0 V to 5.5 V)
