The 74ABT16500C is a high-performance BiCMOS Device which combines low static and dynamic power dissipation with high speed and high output drive. This device is an 18-bit universal transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. Data flow in each direction is controlled by output enable (OEAB and OEBA), latch enable (LEAB and LEBA), and clock (CPAB and CPBA) inputs. For A-to-B data flow, the device operates in the transparent mode when the CPAB input is high and the CPBA input is low. In this mode, the 74ABT16500C drives the outputs of the A-side bus with the data received on the A-side inputs. For B-to-A data flow, the device operates in the latched mode when the CPBA input is high and the CPAB input is low. In this mode, the outputs of the B-side bus are latched by the data received on the B-side inputs.
The document describes the 74ABT16500C and 74ABTH16500C as high-performance BiCMOS devices combining low power dissipation with high speed and output drive. These are 18-bit universal transceivers featuring non-inverting 3-State bus compatible outputs for both send and receive directions, controlled by output enable, latch enable, and clock inputs.
