74VHCT374ASJ

八路D型IP- FL佛罗里达州运与三态输出 Octal D-Type Flip-Flop with 3-STATE Outputs

General Description

The VHCT374A is an advanced high speed CMOS octal flip-flop with 3-STATE output fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintain ing the CMOS low power dissipation. This 8-bit D-type flip

flop is controlled by a clock input CP and an output enable input OE. When the OEinput is HIGH, the eight outputs are in a high impedance state. Protection circuits ensure that 0V to 7V can be applied to the input and output Note 1 pins without regard to the supply voltage. This device can be used to interface 3V to 5V systems and two supply systems such as battery backup. This circuit prevents device destruction due to mismatched supply and input voltages.
