TC7WT125FU
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7WT125FU
Dual Bus Buffer
The TC7WT125FU is a high speed CMOS Dual Bus Buffers
fabricated with silicon gate CMOS technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The input threshold levels are compatible with TTL output
voltage.
The require 3-state control input G to be set high to place the
output Y into the high impedance.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.

Note: 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).

CPD
(Note)
Note: CPD is defined as the value of internal equivalent capacitance which is calculated from the operating current
consumption without load.
Average operating current can be obtained by the equation:
ICC (opr) = CPD • VCC • fIN + ICC/2 (per gate)
