Description
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.
Features
- 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.
