TC74HC173AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC173AP,TC74HC173AF Quad D-Type Register (3-state) The TC74HC173A is a high speed CMOS D-TYPE 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 a 4-bit register consisting of D-type flip-flops and 3-state buffers. The four flip-flops are controlled by a common clock input (CK) and a common clear input (CLR). Signals applied to the data inputs (D1~D4) are stored in the respective flip-flops on the positive going transition of CK when clock control inputs (G1, G2) are held low. The clear function is asynchronous to CK and active on a high level. The stored data are enabled to each outputs when output control inputs (M, N) are held low, else the outputs are high impedance state. All inputs are equipped with protection circuits against static discharge or transient excess voltage.

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 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C shall be applied until 300 mW. 3 2007-10-01 TC74HC173AP/AF Operating Ranges (Note) Characteristics Symbol Rating Unit Supply voltage VCC 2~6 V Input voltage VIN 0~VCC V VOUT 0~VCC V −40~85 °C Output voltage Operating temperature Topr 0~1000 (VCC = 2.0 V) Input rise and fall time 0~500 (VCC = 4.5 V) tr, tf ns 0~400 (VCC = 6.0 V) Note: The operating ranges must be maintained to ensure the normal operation of the device.
