SN75ALS057N

梯形波接口总线收发器 TRAPEZOIDAL-WAVEFORM INTERFACE BUS TRANSCEIVERS

The SN75ALS056 is an eight-channel, monolithic, high-speed, advanced low-power Schottky ALS device designed for two-way data communication in a densely populated backplane. The SN75ALS057 is a four-channel version with independent driver-input Dn and receiver-output Rn pins and a separate driver disable for each driver En.

These transceivers feature open-collector driver outputs with series Schottky diodes to reduce capacitive loading to the bus. By using a 2-V pullup termination on the bus, the output signal swing is approximately 1 V, which reduces the power necessary to drive the bus load capacitance. The driver outputs generate trapezoidal waveforms that reduce crosstalk between channels. The drivers are capable of driving an equivalent dc load as low as 18.5 . The receivers have internal low-pass filters to further improve noise immunity.

The SN75ALS056 and SN75ALS057 are characterized for operation from 0°C to 70°C. View datasheet View product folder
