General description

The 74ABT652A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive.

The 74ABT652A transceiver/register consists of bus transceiver circuits with 3-state outputs, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or the internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin (CPAB or CPBA) goes HIGH. Output Enable (OEAB, OEBA) and Select (SAB, SBA) pins are provided for bus management.

Features and benefits

■ Power-up reset

■ Output capability: +64 mA to −32 mA

■ Latch-up protection exceeds 500 mA per JESD78B class II level A

■ ESD protection:

♦ HBM JESD22-A114F exceeds 2000 V

♦ MM JESD22-A115-A exceeds 200 V

74ABT652ADB属于集成电路（IC） > 缓冲器，驱动器，接收器，收发器。恩智浦半导体公司制造生产的74ABT652ADB缓冲器，驱动器，接收器，收发器逻辑缓冲器、驱动器、接收器和收发器允许隔离对某个电路的逻辑信号的访问，以用于另一电路。缓冲器将其输入信号（不变或反相）传递到其输出，并可能用于清除弱信号或驱动负载。在布尔逻辑仿真器中，缓冲器主要用于增加传播延迟。逻辑接收器和收发器允许在数据总线之间进行隔离通信。
