Low-Voltage 16-Bit Bus Transceiver/Register with Bushold
The TC74VCXHR162652FT is a high-performance CMOS
16-bit bus transceiver/register. 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.
This device is bus transceiver with 3-state outputs, D-type
flip-flops, and control circuitry arranged for multiplexed
transmission of data directly from the internal registers.
The 26-Ω series resistor helps reducing output overshoot and
undershoot without external resistor.
The A, B data inputs include active bushold circuitry,
Weight: 0.25 g (typ.)
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.

Function
The output functions of A and B Busses are
disabled.
Both A and B Busses are used as inputs to
the internal flip-flops. Data on the Bus will be
stored on the rising edge of the Clock.
The data on the A bus are displayed on the
B bus.
The data on the A bus are displayed on the
B Bus, and are stored into the A storage
flip-flops on the rising edge of CAB.
The data in the A storage flop-flops are
displayed on the B Bus.
The data on the A Bus are stored into the A
storage flip-flops on the rising edge of CAB,
and the stored data propagate directly onto
the B Bus.
The data on the B Bus are displayed on the
A bus.
The data on the B Bus are displayed on the
A Bus, and are stored into the B storage
flip-flops on the rising edge of CBA.
The data in the B storage flip-flops are
displayed on the A Bus.
The data on the B Bus are stored into the B
storage flip-flops on the rising edge of CBA,
and the stored data propagate directly onto
the A Bus.
The data in the A storage flop-flops are
displayed on the B Bus, and the data in the
B storage flop-flops are displayed on the A.
X: Don’t care
Z: High impedance
Qn: The data stored into the internal flip-flops by most recent low to high transition of the clock inputs.
*: The clocks are not internally gated with either OEAB or OEBA .
Therefore, data on the A and/or B busses may be clocked into the storage flip-flops at any time.

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.
