DS89C21規(guī)格書詳情
描述 Description
The DS89C21 is a differential CMOS line driver and receiver pair, designed to meet the requirements of TIA/EIA-422-A (RS-422) electrical characteristics interface standard. The DS89C21 provides one driver and one receiver in a minimum footprint. The device is offered in an 8-pin SOIC package.
The CMOS design minimizes the supply current to 6 mA, making the device ideal for use in battery powered or power conscious applications.
The driver features a fast transition time specified at 2.2 ns, and a maximum differential skew of 2 ns making the driver ideal for use in high speed applications operating above 10?MHz.
The receiver can detect signals as low as 200 mV, and also incorporates hysteresis for noise rejection. Skew is specified at 4 ns maximum.
The DS89C21 is compatible with TTL and CMOS levels (DI and RO).
特性 Features
? Meets TIA/EIA-422-A (RS-422) and CCITT V.11 Recommendation
? Guaranteed AC Parameters:
? Maximum Receiver Skew 4.0 ns
? Extended Temperature Range:??40°C to +85°C
? Operates over 20 Mbps
? Receiver OPEN Input Failsafe Feature
簡介
DS89C21屬于集成電路(IC)的驅(qū)動(dòng)器接收器收發(fā)器。由TI制造生產(chǎn)的DS89C21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,以通過延長電纜或印制線進(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,這些功能對于通信用途可能并非絕對必要,但對于可能的使用環(huán)境卻是明智之選。
