SN75140 Datasheet | Texas Instruments

description This device consists of a dual single-ended line receiver with TTL-patible strobes and outputs. The reference voltage (switching threshold) is applied externally and can be adjusted from 1.5 V to 3.5 V, making it possible to optimize noise immunity for a given system design. Due to the low input current (less than 100 µA), the device is suited ideally for party-line (data-bus) systems. The SN75140 has a mon reference-voltage pin and a mon strobe. The SN75140 is characterized for operation from 0°C to 70°C. logic symbol‡ FUNCTION TABLE (each receiver) LINE INPUT STROBE OUTPUT ≤ Vref - 100 m V ≥ Vref + 100 m V H = high level, L = low level, X = irrelevant 2 STRB 3 1LINE REF 6 5 2LINE ≥1 1OUT ≥1 2OUT ‡ This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12.
