| LESHAN RADIO COMPANY, LTD. Schmitt-Trigger Inverter/ CMOS Logic Level Shifter with LSTTL-Compatible Inputs L74VHC1GT14 The L74VHC1GT14 is a single gate CMOS Schmitt-trigger inverter 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 device input is compatible with TTL-type input thresholds and the output has a full 5 V CMOS level output swing. The input protection circuitry on this device allows overvoltage tolerance on the input, allowing the device to be used as a logic-level translator from 3.0 V CMOS logic to 5.0 V CMOS Logic or from 1.8 V CMOS logic to 3.0 V CMOS Logic while operating at the high-voltage power supply. The L74VHC1GT14 input structure provides protection when voltages up to 7 V are applied, regardless of the supply voltage. This allows the L74VHC1GT14 to be used to interface 5 V circuits to 3 V circuits. The output structures also provide protection when V CC = 0 V. These input and output structures help prevent device destruction caused by supply voltage - input/output voltage mismatch, battery backup, hot insertion, etc. The LMC74VHC1GT14 can be used to enhance noise immunity or to square up slowly changing waveforms. * High Speed: t PD = 4.5 ns (Typ) at V CC = 5 V * Low Power Dissipation: I CC = 2 mA (Max) at T A = 25C * TTL-Compatible Inputs: V IL = 0.8 V; V IH = 2.0 V * CMOS-Compatible Outputs: V OH > 0.8 V CC ; V OL < 0.1 V CC @ Load * Power Down Protection Provided on Inputs and Outputs * Balanced Propagation Delays * Pin and Function Compatible with Other Standard Logic Families * Chip Complexity: FETs = 100; Equivalent Gates = 25 MARKING DIAGRAMS 5 4 1 2 3 VCd SC-70/SC-88A/SOT-353 DF SUFFIX Pin 1 d = Date Code 5 4 Figure 1.

C PD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: I CC(OPR) = C PD * V CC * f in + I CC . C PD is used to determine the no- load dynamic power consumption; P D = C PD * V CC 2 * f in + I CC * V CC . 3/6 LESHAN RADIO COMPANY, LTD. L74VHC1GT14 3.0V V OH V OL Figure 4.
