SN75ALS057 Overview
Key Specifications
Package: SOIC
Mount Type: Surface Mount
Pins: 20
Operating Voltage: 5 V
Description
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).
Key Features
- open-collector driver outputs with series Schottky diodes to reduce capacitive loading to the bus
- 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 Ω
- 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
