D OR N PACKAGE (TOP VIEW) The SN75125 and SN75127 are monolithic seven-channel line receivers designed to satisfy the requirements of the IBM System 360/370 input/output interface specifications. Special low-power design and Schottky-clamped transistors allow for low supply-current requirements while maintaining fast switching speeds and high-current TTL outputs. The SN75125 and SN75127 are characterized for operation from 0°C to 70°C. logic symbols† 1A 2A 3A 4A 5A 6A 7A GND 1 2 3 4 5 6 7 8 16 VCC 15 1Y 14 2Y 13 3Y 12 4Y 11 5Y 10 6Y 9 7Y THE SN75125 IS NOT RECOMMENDED FOR NEW DESIGN 1A 1 2A 2 3A 3 4A 4 5A 5 6A 6 7A 7 SN75125 16 1Y 9 2Y 14 3Y 13 4Y 12 5Y 11 6Y 10 7Y 1A 1 2A 2 3A 3 4A 4 5A 5 6A 6 7A 7 SN75127 15 1Y 14 2Y 13 3Y 12 4Y 11 5Y 10 6Y 9 7Y † These symbols are in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12.
