SN75129 Datasheet | Texas Instruments

description The SN75128 and SN75129 are eight-channel line receivers designed to satisfy the requirements of the input-output interface specification for IBM 360/370. Both devices feature mon strobes for each group of four devices. The SN75128 has active-high strobes; the SN75129 has active-low strobes. Special low-power design and Schottky-diode-clamped transistors allow low supply-current requirements while maintaining fast switching speeds and high-current TTL outputs. For new IBM 360/370 interface designs, see the SN751730. The SN75128 and SN75129 are characterized for operation from 0°C to 70°C. logic symbols† SN75128 1 1S 11 2S EN1 EN2 1 1S 11 2S EN1 EN2 2 1A 3 2A 4 3A 5 4A 6 5A 7 6A 8 7A 9 8A 19 1 1Y 18 2Y 17 3Y 16 4Y 15 2 5Y 14 6Y 13 7Y 12 8Y 2 1A 3 2A 4 3A 5 4A 6 5A 7 6A 8 7A 9 8A 1 19 1Y 18 2Y 17 3Y 16 4Y 2 15 5Y 14 6Y 13 7Y 12 8Y † These symbols are in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12.
