DESCRIPTION
The 74ALVT16501 is a high-performance BiCMOS product
designed for V
CC
operation at 2.5V and 3.3V with I/O compatibility
up to 5V.
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).
Active bus-hold circuitry is provided to hold unused or floating data
inputs at a valid logic level.
