MC74VHCT50A Noninverting Buffer / CMOS Logic Level Shifter with LSTTLCompatible Inputs The MC74VHCT50A is a hex noninverting 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 internal circuit is composed of three stages, including a buffered output which provides high noise immunity and stable output. The device input is compatible with TTLtype 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 logiclevel 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 highvoltage power supply. The MC74VHCT50A input structure provides protection when voltages up to 7 V are applied, regardless of the supply voltage. This allows the MC74VHCT50A 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. http://onsemi.com 14LEAD SOIC D SUFFIX CASE 751A 14LEAD TSSOP DT SUFFIX CASE 948G 14LEAD SOIC EIAJ M SUFFIX CASE 965 PIN CONNECTION AND MARKING DIAGRAM (Top View) VCC 14 A6 13 Y6 12 A5 11 Y5 10 A4 9 Y4 8 High Speed: tPD = 3.5 ns (T……
