DESCRIPTION
The 74ABT16501A high-performance BiCMOS device 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 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).
