TC7PB54FC/FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7PB54FC, TC7PB54FK
Single 1-of-3 Demultiplexer with N-channel pull-down MOSFET
The TC7PB54 is a single 1-of-3 high-speed CMOS demultiplexer designed for low-voltage applications. The low ON-resistance of the switch allows the input (COM) to be connected to the outputs (Ch0 and Ch1) while maintaining CMOS low power dissipation. The device uses P-channel MOSFETs for the switch block between the input and output pins. The single-input multiplexer can direct the potential supplied on the COM pin to one of the Ch0 to Ch2 pins depending on the combined state of control pins A and B. The unused Chx pins are clamped to ground using an N-channel MOSFET.
All inputs are equipped with protection circuits against static discharge.

Note 1:
Exceeding any of the absolute maximum ratings, even briefly, may 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 1: The operating ranges must be maintained to ensure the normal operation of the device. Unused inputs must be tied to either VCC or GND.
Note 2: Ensure that the voltages on the COM and Ch pins do not exceed VCC + 0.3 V even during a power-up sequence or when the power decreases.
