NL17SHT126

NL17SHT126 Noninverting Buffer / CMOS Logic Level Shifter with LSTTL−Compatible Inputs The NL17SHT126 is a single gate noninverting 3−state buffer fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. The NL17SHT126 requires the 3−state control input (OE) to be set Low to place the output into the high impedance state. 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 V CMOS logic to 5 V CMOS Logic or from 1.8 V CMOS logic to 3 V CMOS Logic while operating at the high−voltage power supply. The NL17SHT126 input structure provides protection when voltages up to 7 V are applied, regardless of the supply voltage. This allows the NL17SHT126 to be used to interface 5 V circuits to 3 V circuits. The output structures also provide protection when VCC = 0 V. These input and output structures help prevent device destruction caused by supply voltage − input/output voltage mismatch, battery backup, hot insertion, etc. Features High Speed: tPD = 3.5 ns (Typ) at VCC = 5 V Low Power Dissipation: ICC = 1 mA (Max) at TA = 25°C TTL−Compatible Inputs: VIL = 0.8 V; VIH = 2 V CMOS−Compatible Outputs: VOH > 0.8 VCC; VOL < 0.1 VCC @Load Power Down Protection...
