HD74LVC16374A
16-bit D-type Flip Flops with 3-state Outputs
ADE-205-122B(Z)
3rd Edition
December 1996
Description
The HD74LVC16374A has sixteen edge trigger D type flip flops with three state outputs in a 48 pin
package. Data at the D inputs meeting set up reguirements, are transferred to the Q outputs on positive
going transitions of the clock input. When the latch enable goes low, data at the D inputs will be retained
at the outputs until latch enable 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)
