MC74VHCT125ADR2G

Буфер, неинвертирующий, 4.5В до 5.5В, SOIC-14.

The MC74VHCT125ADR2G is a quad Bus Buffer with 3-state control inputs. It is a high speed CMOS quad bus buffer fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent bipolar Schottky TTL while maintaining CMOS low power dissipation. It requires the 3-state control input (OE) to be set High to place the output into the high impedance state. The VHCT inputs are compatible with TTL levels. This device can be used as a level converter for interfacing 3.3 to 5V, because it has full 5V CMOS level output swings. The output structures also provide protection when VCC = 0V. These input and output structures help prevent device destruction caused by supply voltage - input/output voltage mismatch, battery backup, hot insertion. The internal circuit is composed of 3-stage, including a buffer output which provides high noise immunity and stable output. The inputs tolerate voltages up to 7V, allowing the interface of 5V systems to 3V systems.
