L74VHC1G132

LESHAN RADIO COMPANY, LTD. 2−Input NAND Schmitt Trigger L74VHC1G132 The L74VHC1G132 is a single gate CMOS Schmitt NAND trigger fabricated with silicon gate CMOS technology.It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. The internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output. The L74VHC1G132 input structure provides protection when voltages up to 7.0 V are applied, regardless of the supply voltage. This allows the L74VHC1G132 to be used to interface 5.0 V circuits to 3.0 V circuits. The L74VHC1G132 can be used to enhance noise immunity or to square up slowly changing waveforms. Features High Speed: tPD = 3.6 ns (Typ) at VCC = 5.0 V Low Power Dissipation: ICC = 1.0 mA (Max) at TA = 25°C Power Down Protection Provided on Inputs Balanced Propagation Delays Pin and Function Compatible with Other Standard Logic Families Chip Complexity: FETs = 68; Equivalent Gates = 16 Pb−Free Packages are Available 5 4 MARKING DIAGRAMS 1 2 3 SC–88A/SOT–353/SC–70 DF SUFFIX M 5 VD M G G 1 IN B 1 IN A 2 GND 3 5 VCC 4 OUT Y 5 4 1 2 3 TSOP–5/SOT–23/SC–59 DT SUFFIX PIN ASSIGNMENT 1 IN B 2 IN A 3 GND 4 OUT Y 5 VCC 5 VD AYW G G 1 Figure 1.
