DESCRIPTION

The 74ACT16245 is an advanced high-speed CMOS 16-BIT BUS TRANSCEIVER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

This IC is intended for two-way asynchronous communication between data buses and the direction of data transmission is determined by DIR input. The enable inputs G can be used to disable the device so that the buses are effectively isolated.

All floating bus terminals during the Z-state must be held HIGH or LOW.

All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

■ HIGH SPEED: tPD = 4.9ns (TYP.) at VCC = 5V

■ LOW POWER DISSIPATION:

ICC = 8µA(MAX.) at TA=25°C

■ COMPATIBLE WITH TTL OUTPUTS

VIH = 2V (MIN.), VIL = 0.8V (MAX.)

■ 50Ω TRANSMISSION LINE DRIVING CAPABILITY

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOH| = IOL = 24mA (MIN)

■ OPERATING VOLTAGE RANGE:

VCC (OPR) = 4.5V to 5.5V

■ IMPROVED LATCH-UP IMMUNITY

74ACT16245属于集成电路（IC） > 缓冲器，驱动器，接收器，收发器。意法半导体（ST）集团制造生产的74ACT16245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。
