DESCRIPTION
The 74ALVT16600 is a high-performance BiCMOS product
designed for V
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
OEBA
), latch enable (LEAB and LEBA), and clock (CPAB and
) inputs. For A-to-B data flow, the device operates in the
CPBA
transparent mode when LEAB is High. When LEAB is Low, the A
data is latched if CPAB
is Low, the A-bus data is stored in the latch/flip-flop on the
High-to-Low transition of CPAB
active. When OEAB
state. The High clock can be controlled with the clock-enable inputs
(CEBA
/CEAB).
Data flow for B-to-A is similar to that of A-to-B but uses OEBA
LEBA and CPBA
Active bus-hold circuitry is provided to hold unused or floating data
inputs at a valid logic level.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability .
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
