CD74HC652 具有三态输出的高速 CMOS 逻辑八路总线收发器/寄存器
CD74HC652 描述
The CD74HC652 and CD74HCT652 three-state, octal-bus transceiver/registers use silicon-gate CMOS technology to achieve operating speeds similar to LSTTL with the low power consumption of standard CMOS integrated circuits. The CD74HC652 and CD74HCT652 have non-inverting outputs. These devices consists of bus transceiver circuits, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the data bus or from the internal storage registers. Output Enables OEAB and OEBA are provided to control the transceiver functions. SAB and SBA control pins are provided to select whether real-time or stored data is transferred. The circuitry used for select control will eliminate the typical decoding glitch that occurs in a multiplexer during the transition between stored and real-time data.
