HD74LV573A

Octal D-type Transparent Latches with 3-state Outputs

ADE-205-279A (Z)

2nd Edition

July 1999

Description

The HD74LV573A 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 for the battery-powered products (e.g., notebook computers), and the low-power consumption extends the battery life.

Features

• VCC = 2.0 V to 5.5 V operation

• All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V)

• All outputs VO (Max.) = 5.5 V (@VCC = 0 V)

• Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)

• Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°C)

• Output current ±8 mA (@VCC = 3.0 V to 3.6 V), ±16 mA (@VCC = 4.5 V to 5.5 V)

1. The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

2. This value is limited to 5.5 V maximum.

3. The maximum package power dissipation was calculated using a junction temperature of 150°C.

2. Waveform-A is for an output with internal conditions such that the output is low except when disabled

by the output control.

3. Waveform-B is for an output with internal conditions such that the output is high except when disabled

by the output control.

4. The output is measured one at a time with one transition per measurement.
