HD74LVC4245A

Octal Bus Transceiver and 3.3 V to 5 V shifters

with 3-state Outputs

ADE-205-683 (Z)

Rev.0

Apr. 2002

Description

The HD74LVC4245A has eight bus transceivers with three state outputs in a 24 pin package. When (DIR)

is high, data flows from the A inputs to the B outputs, and when (DIR) is low, data flows from the B inputs

to the A outputs. A and B bus are separated by making enable input (OE) high level. And this product has

two terminals (V_CCA, V_CCB), V_CCA(5V) is connected with control input and A bus side, V_CCB(3.3V) connected

with B bus side. V_CCAand V_CCBare isolated. This allows for translation from a 3.3 V to a 5 V environment,

and vice versa. 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

•

This product function as level shift transceiver that change V_CCAinput level to V_CCBoutput level, V_CCB

input level to V_CCAoutput level by providing different supply voltage to V_CCAand V_CCB

•

This product is able to the power management: Turn on and off the supply on V_CCBside with providing

the supply of V_CCA. (Enable input (OE): High level )

V_CCA= 4.5 V to 5.5 V, V_CCB= 2.7 V to 3.6 V

•

All control input V_I(max) = 5.5 V (@V_CCA= 0 V to 5.5 V)

All A bus side input outputs V_I/O(max) = 5.5 V

(@V_CCA= 0 V or output off state)

•

All B bus side input outputs V_I/O(max) = 3.6 V

(@V_CCB= 0 V or output off state)

High output current

A bus side : 24 mA (@V_CCA= 4.5 V to 5.5 V)

B bus side :

12 mA (@V_CCB= 2.7 V)

24 mA (@V_CCB= 3.0 V to 3.6 V)
