HD74LVC533
Octal D-type Transparent Latches with 3-state Outputs
ADE-205-070B(Z)
Rev.2
September 1995
Description
The HD74LVC533 has eight D type latches with three state outputs in a 20 pin package. When the latch
enable input is high, the Q outputs will follow the D inputs. 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)
• 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)
