HD74LVC374A
Octal D-type Flip Flops with 3-state Outputs
ADE-205-113B(Z)
3rd Edition
December 1996
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.
Features
• 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)
