SN75ALS057 梯形波接口总线收发器
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
