74LVT16501A

3.3 V LVT 18-bit universal bus transceiver; 3-state

Rev. 04 — 19 May 2006

Product data sheet

1. General description

The 74LVT16501A is a high-performance BiCMOS product designed for V

operation at

3.3 V. 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 LEAB is HIGH.

When LEAB is LOW, the A-bus data is latched if CPAB is held at a HIGH or LOW 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).

Active bus hold circuitry is provided to hold unused or ﬂoating data inputs at a valid logic

level.
