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
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)
