General Description
The HD74ALVCH162543 can be used as two 8-bit transceivers or one 16-bit transceiver.
Separate latch enable (LEAB or LEBA) and output enable ( OEAB or OEBA ) inputs are provided for each register to permit independent control in either direction of data flow.
Key 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).
- High output current ±12 mA (@VCC = 3.0 V).
- Bus hold on data inputs eliminates the need for external pullup / pulldown resistors.
- All outputs have equivalent 26 Ω series resistors, so no external resistors are required. HD74ALVCH162543 Function Table.
- 2 Inputs CEAB H X L L L LEAB X X H L L OEAB X H.
