Octal D-Type Latch with 3-State Output
The TC74VHCT573A is an advanced high speed CMOS OCTAL LATCH with 3-STATE OUTPUT fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power dissipation.
This 8-bit D-type latch is controlled by a latch enable input (LE) and a output enable input ( OE ).
When the OE input is high, the eight outputs are in a high impedance state.
The input voltage are compatible with TTL output voltage. This device may be used as a level converter for interfacing 3.3 V to 5 V system. Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and input/output voltages such as battery back up, hot board insertion, etc.
Note: Output in off-state
Features
High speed: tpd = 7.7 ns (typ.) at VCC = 5 V Low power dissipation: ICC = 4 µA (max) at Ta = 25°C Compatible with TTL outputs: VIL = 0.8 V (max)
VIH = 2.0 V (min) Power down protection is provided on all inputs and outputs. Balanced propagation delays: tpLH ∼− tpHL Low noise: VOLP = 1.6 V (max) Pin and function compatible with the 74 series
(74AC/HC/F/ALS/LS etc.) 573 type.
