74VCX1632245屬于集成電路（IC）的驅(qū)動(dòng)器接收器收發(fā)器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的74VCX1632245驅(qū)動(dòng)器，接收器，收發(fā)器該系列產(chǎn)品的主要功能是提供必需的硬件資源，以通過(guò)延長(zhǎng)電纜或印制線進(jìn)行通信。確切的功能會(huì)因所采用的通信協(xié)議而異，可能包括諸如瞬態(tài)抑制之類的功能，這些功能對(duì)于通信用途可能并非絕對(duì)必要，但對(duì)于可能的使用環(huán)境卻是明智之選。

DESCRIPTION

The 74VCX1632245 is a dual supply low voltage CMOS 16-BIT BUS TRANSCEIVER fabricated with sub-micron silicon gate and five-layer metal wiring C2MOS technology. Designed for use as an interface between a 3.3V bus and a 2.5V or 1.8V bus in a mixed 3.3V/1.8V,3.3V/2.5V and 2.5V/1.8V supply systems, it achieves high speed operation while maintaining the CMOS low power dissipation.

■ HIGH SPEED: tPD = 4.4ns (MAX.) at TA=85°C

VCCA = 3.0V VCCB = 2.3V

■ LOW POWER DISSIPATION:

ICCA = ICCB = 20μA(MAX.) at TA=85°C

■ SYMMETRICAL OUTPUT IMPEDANCE:

|IOHA| = IOLA = 8mA MIN at

VCCA = 3.0V VCCB = 1.65V or 2.3V

|IOHA| = IOLA = 18mA MIN at

VCCA = 2.3V VCCB = 1.65V)
