TC74VCXH162827FT
Low-Voltage 20-Bit Bus Buffer with Bushold
The TC74VCXH162827FT is a high-performance CMOS 20-bit
bus buffer. 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 TC74VCXH162827FT is composed of two 10-bit sections
with separate output-enable signals. For either 10-bit buffer
section, the two output-enable (1OE1 and 1OE2 or 2OE1 and
2OE2) inputs must both be low for the corresponding Y outputs
to be active. When the OE input is high, the outputs are in a
high impedance state. This device is designed to be used with
Weight: 0.25 g (typ.)
3-state memory address drivers, etc.
The 26-Ω series resistor helps reducing output overshoot and
undershoot without external resistor.
The A 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.
