18-bit universal bus transceiver; 3-state

Rev. 7 — 24 November 2021

Product data sheet

1. General description

The 74ALVCH16501 is an 18-bit universal transceiver with bus hold inputs and 3-state outputs.

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 LEAB is HIGH. When LEAB is LOW, the A data is latched if CPAB is held

at a HIGH or LOW logic level. If LEAB is LOW, the A-bus data is stored in the latch/flip-flop on the

LOW-to-HIGH transition of CPAB. When OEAB is HIGH, the outputs are active. When OEAB is

LOW, the outputs are in the high-impedance state. Data flow for B-to-A is similar to that of A-to-B

but uses OEBA, LEBA and CPBA. The output enables are complimentary (OEAB is active HIGH

and OEBA is active LOW). This device is fully specified for partial power down applications using

I_OFF. The I_OFFcircuitry disables the output, preventing the potentially damaging backflow current

through the device when it is powered down.
