The TC74AC374 and TC74AC534 are advanced high speed CMOS OCTAL FLIP-FLOPS fabricated with silicon gate and double-layer metal wiring C2MOS technology.
They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.
These 8-bit D-type flip-flops are controlled by a clock input (CK) and a output enable input ( OE ).
When the OE input is high, the eight outputs are in a high impedance state.
The TC74AC374 has non-inverting outputs, and TC74AC534 has inverting outputs.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features
• High speed: fmax = 200 MHz (typ.) at VCC = 5 V • Low power dissipation: ICC = 8 μA (max) at Ta = 25°C • High noise immunity: VNIH = VNIL = 28% VCC (min) • Symmetrical output impedance: |IOH| = IOL = 24 mA (min)
Capability of driving 50 Ω transmission lines. • Balanced propagation delays: tpLH ∼− tpHL • Wide operating voltage range: VCC (opr) = 2 to 5.5 V • Pin and function compatible with 74F374/534

Note 1:
Exceeding any of the absolute maximum ratings, even briefly, 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: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C, a derating factor of −10 mW/°C should be applied up to 300 mW.
