| TC74HC166AP/AF/AFN TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC166AP,TC74HC166AF,TC74HC166AFN 8-Bit Shift Register (P-IN, S-OUT) The TC74HC166A is a high speed CMOS 8-BIT PARALLEL/SERIAL-IN, SERIAL-OUT SHIFT REGISTER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. It consists of parallel-in or serial-in, serial-out 8-bit shift register with a gated clock input and an overriding clear input. The parallel-in or serial-in modes are controlled by the SHIFT/ LOAD input. When the SHIFT/ LOAD input is held high, the serial data input is enabled and the eight flip-flops perform serial shifting on each clock pulse. When held low, the parallel data inputs are enabled and synchronous loading occurs on the next clock pulse. Clocking is accomplished on the low-to-high transition of the clock pulse. The CK-INH input should be shifted high only while the CK input is held high. A direct clear input overrides all other inputs, includng the clock, and sets all the flip-flops to zero. Functional details are shown in the truth table and the timing charts. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Note: xxxFN (JEDEC SOP) is not available in Japan.

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: 500 mW in the range of Ta = -40 to 65C. From Ta = 65 to 85C a derating factor of -10 mW/C shall be applied until 300 mW. 4 2007-10-01 TC74HC166AP/AF/AFN Operating Ranges (Note) Characteristics Supply voltage Input voltage Output voltage Operating temperature Symbol VCC VIN VOUT Topr Rating 2 to 6 0 to VCC 0 to VCC -40 to 85 Unit V V V C 0 to 1000 (VCC = 2.0 V) Input rise and fall time tr, tf 0 to 500 (VCC = 4.5 V) 0 to 400 (VCC = 6.0 V) ns Note: The operating ranges must be maintained to ensure the normal operation of the device.
