TC74HC573AF(EL,F)

The TC74HC573AF is a high speed CMOS OCTAL LATCH with 3-STATE OUTPUT fabricated with silicon gate C²MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. Its 8-bit D-type latch is controlled by a latch enable input (LE) and an output enable input ( OE\ ). When the OE\ input is high, the eight outputs are in a high impedance state. All inputs are equipped with protection circuits against static discharge or transient excess voltage.

• High speed: tPd = 13 ns (typ.) at Vcc = 5 V
• Low power dissipation: Icc = 4 µA (max) at Ta = 25°C
• High noise immunity: Vnih = Vnil = 28% Vcc (min)
• Output drive capability: 15 LSTTL loads
• Symmetrical output impedance: |Ioh| = Iol = 6 mA (min)
• Balanced propagation delays: tpLH - tpHL
• Wide operating voltage range: Vcc (opr) = 2 to 6 V
• Pin and function compatible with 74LS573
• Package: SOP20
