74ABT652CMSA集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

General Description

The ABT652 consists of bus transceiver circuits with D-type flip-flops and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes to HIGH logic level. Output Enable pins (OEAB, OEBA) are provided to control the transceiver function.

特性 Features

■ Independent registers for A and B buses

■ Multiplexed real-time and stored data

■ A and B output sink capability of 64 mA, source

capability of 32 mA

■ Guaranteed output skew

■ Guaranteed multiple output switching specifications

■ Output switching specified for both 50 pF and 250 pF loads

■ Guaranteed simultaneous switching noise level and

dynamic threshold performance

■ Guaranteed latchup protection

■ High impedance glitch free bus loading during entire

power up and power down cycle

■ Nondestructive hot insertion capability
