Additional preview pages of the HD74ALVCH16245 datasheet.

The HD74ALVCH16245 is designed for asynchronous communication between data buses.

The control function implementation minimizes external timing requirements.

This device can be used as two 8-bit transceivers or one 16-bit transceiver.

VCC = 2.3 V to 3.6 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).
Bus hold on data inputs eliminates the need for external pullup / pulldown resistors Function Table Inputs OE L L H H : High level L : Low level X : Immaterial DIR L H X B data to A bus A data to B bus Isolation Operation HD74ALVCH16245 Pin Arrangement 1DIR 1 1B1 2 1B2 3 GND 4 1B3 5 1B4 6 VCC 7 1B5 8 1B6 9 GND 10 1B7.
