Low-Voltage 16-Bit Registered Transceiver with Bushold
The TC74VCXHR162543FT is a high-performance CMOS
16-bit registered transceiver. Designed for use in 1.8-V, 2.5-V or
3.3-V systems, it achieves high-speed operation while
maintaining the CMOS low power dissipation.
The TC74VCXHR162543FT can be used as two 8-bit
transceivers or one 16-bit transceiver. Separate latch-enable
(LEAB or LEBA) and output-enable (OEAB or OEBA) inputs are
provided for each register to permit independent control in either
direction of data flow.
The A-to-B enable (CEAB) input must be low in order to enter
Weight: 0.25 g (typ.)
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 Alatches 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.
Data flow from B to A is similar but requires using the CEBA, LEBA, and OEBA inputs.
When the OE input is high, the outputs are in a high-impedance state. This device is designed to be used with
3-state memory address drivers, etc.
The 26-Ω series resistor helps reducing output overshoot and undershoot without external resistor.
The A, B data inputs include active bushold circuitry, eliminating the need for external pull-up resistors to hold
unused or floating data inputs at a valid logic level.
All inputs are equipped with protection circuits against static discharge.

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note 2: OFF state
Note 3: High or low state. IOUT absolute maximum rating must be observed.
