Low-Voltage 18-Bit Universal Bus Transceiver with 3.6-V Tolerant Inputs and Outputs
The TC74VCXR162600FT is a high-performance CMOS 18-bit
universal bus 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.
It is also designed with overvoltage tolerant inputs and outputs
up to 3.6 V.
Data flow in each direction is controlled by output-enable
(OEAB and OEBA), latch-enable (LEAB and LEBA), and clock
(CKAB and CKBA) inputs. The clock can be controlled by the
clock-enable (CKENAB and CKENBA) inputs.
Weight: 0.25 g (typ.)
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 CKAB 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 high-to-low transition of CKAB.
Data flow for B to A is similar to that of A to B but uses OEBA, LEBA, CKBA, and CKENBA.
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.
All inputs are equipped with protection circuits against static discharge.

•
Output current : IOH/IOL = ±12 mA (min) (VCC = 3.0 V)
: IOH/IOL = ±8 mA (min) (VCC = 2.3 V)
: IOH/IOL = ±4 mA (min) (VCC = 1.8 V)
•
•
Latch-up performance: −300 mA
ESD performance: Machine model ≥ ±200 V
Human body model ≥ ±2000 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.

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).
