TC74VHCT574AF Overview
It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This 8-bit D-type flip-flop is controlled by a clock input (CK) and an output enable input ( OE ). When the OE input is high, the eight outputs are in a high impedance state.
TC74VHCT574AF Key Features
- High speed: fmax = 140 MHz (typ.) at VCC = 5 V
- Low power dissipation: ICC = 4 μA (max) at Ta = 25°C
- patible with TTL inputs
- Power down protection is provided on all inputs and outputs
- Balanced propagation delays: tpLH ≈ tpHL
- Low noise: VOLP = 1.5 V (max)
- Pin and function patible with the 74 series (74AC/HC/F/ALS/LS etc.) 574 type
