flow.
data from A or to output data from B. If CEAB is low and LEAB is low, the A-to-B latches are transparent; a
subsequent low-to-high transition of LEAB puts the A latches in the storage mode. With CEAB and OEAB both low,
the 3-state B outputs are active and reflect the data present at the output of the A latches.

Features (Note)
The TC74VCX16543FT is a high performance CMOS 16-bit
It is also designed with overvoltage tolerant inputs and outputs
The TC74VCX16543FT can be used as two 8-bit transceivers or
The A-to-B enable (CEAB) input must be low in order to enter
Data flow from B to A is similar but requires using the CEBA, LEBA, and OEAB inputs.
When the OE input is high, the outputs are in a high-impedance state. This device is designed to be used with
All inputs are equipped with protection circuits against static discharge.
Low-voltage operation: V
High-speed operation: t
Output current: I
Latch-up performance: −300 mA
ESD performance: Machine model ≥ ±200 V
Package: TSSOP
Bidirectional interface between 2.5 V and 3.3 V signals.
3.6-V tolerant function and power-down protection provided on all inputs and outputs
Note:
Do not apply a signal to any bus pins when it is in the output mode. Damage may result.
All floating (high impedance) bus pins must have their input level fixed by means of pull-up or pull-down
resistors.
