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.

Absolute Maximum Ratings (Note 1)
Characteristics Power supply voltage DC input voltage (A, B) DC switch voltage (COM and Ch) Input diode current (A, B) Output diode current (COM and Ch) Switch I/O current (COM to Ch) N-channel MOSFET current Power dissipation DC VCC/ground current Storage temperature (Note 2) Symbol VCC VIN VS IIK IS IOUT PD ICC/IGND Tstg Rating -0.5 to 4.6 -0.5 to 4.6 -0.5 to VCC + 0.5 -25 25 128 25 150 (CSON8) 200 (SSOP8) 50 -65 to 150 Unit V V V mA mA mA mA mW mA C
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 2: N-channel MOSFET allowable current to clamp the unused pin to ground.
Operating Ranges (Note 1)
Characteristics Power supply voltage Input voltage (A, B) DC switch voltage (COM and Ch) (Note 2) Operating temperature Input rise and fall time (A, B) Symbol VCC VIN VS Topr dt/dv Rating 2.0 to 3.6 0 to 3.6 0 to VCC + 0.3 -40 to 85 0 to 10 Unit V V V C ns/V
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.
