MC74VHCT125A Quad Bus Buffer with 3State Control Inputs The MC74VHCT125A is a high speed CMOS quad bus buffer fabricated with silicon gate CMOS technology. It achieves high speed www.onsemi.com operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. The MC74VHCT125A requires the 3state control input (OE) to be MARKING DIAGRAMS set High to place the output into the high impedance state. The VHCT inputs are compatible with TTL levels. This device can 14 be used as a level converter for interfacing 3.3 V to 5.0 V, because it SOIC14 VHCT125AG has full 5.0 V CMOS level output swings. D SUFFIX AWLYWW CASE 751A The VHCT125A input structures provide protection when voltages 1 1 between 0 V and 5.5 V are applied, regardless of the supply voltage. The output structures also provide protection when V = 0 V. These CC 14 input and output structures help prevent device destruction caused by VHCT supply voltage input/output voltage mismatch, battery backup, hot TSSOP14 125A DT SUFFIX insertion, etc. ALYW CASE 948G The internal circuit is composed of three stages, including a buffer 1 output which provides high noise immunity and stable output. The 1 inputs tolerate voltages up to 7.0 V, allowing the interface of 5.0 V A = Assembly Location systems to 3.0 V systems.
