Overview
TC74VHCT573AF/AFW/AFT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHCT573AF,TC74VHCT573AFW,TC74VHCT573AFT 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.
Note: xxxFW (JEDEC SOP) is not available in Japan.
