General description

The 74F543 octal latched transceiver contains two sets of D-type latches for temporary storage of data flowing in either direction. Separate latch enable (LEAB, LEBA) and output enable (OEAB, OEBA) inputs are provided for each register to permit independent control of data transfer in either direction. The A outputs are guaranteed to sink 24 mA while the B outputs are rated for 64 mA.

Features

■ Combines 74F245 and 74F373 type functions in one device

■ 8-bit octal transceiver with D-type latch

■ Back-to-back registers for storage

■ Separate controls for data flow in each direction

■ A output capability: +20 mA to −3 mA

■ B output capability: +64 mA to −15 mA

■ 3-state outputs for bus-oriented applications

N74F543DB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N74F543DB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。
