HD74LV245A

Octal Bus Transceivers with 3-state Outputs

ADE-205-247 (Z)

1st Edition

March 1999

Description

The HD74LV245A has eight buffers with three-state outputs in a 20-pin package. When DIR is high, data

is transferred from the A inputs to the B outputs, and when DIR is low, data is transferred from the B inputs

to the A outputs. The A and B buses are separated by making the enable input (OE) high level. Low-

voltage operation is suitable for battery-powered products (e.g., notebook computers), and the low power

consumption extends the battery life.

Features

•

= 2.0 V to 5.5 V operation

•

All inputs V

(Max.) = 5.5 V (@V

= 0 V to 5.5 V)

•

All outputs V

(Max.) = 5.5 V (@V

= 0 V)

•

Typical V

ground bounce < 0.8 V (@V

= 3.3 V, Ta = 25°C)

•

Typical V

undershoot > 2.3 V (@V

= 3.3 V, Ta = 25°C)

•

Output current ±8 mA (@V

= 3.0 V to 3.6 V), ±16 mA (@V

= 4.5 V to 5.5 V)
