Octal D-Type Latch with 3-State Output
The TC74HCT573A 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 inputs are compatible with TTL, NMOS, and CMOS output
voltage levels.
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.
Features
• High speed: t_pd = 18 ns (typ.) at V_CC = 5 V
• Low power dissipation: I_CC = 4 μA (max) at Ta = 25°C
• Compatible with TTL outputs: V_IL = 0.8 V (max)
V_IH = 2.0 V (min)
• Output drive capability: 15 LSTTL loads
• Symmetrical output impedance: |I_OH| = I_OL = 6 mA (min)
• Balanced propagation delays: t_pLH ^∼− t_pHL
• Pin and function compatible with 74LS573
