I/O Bus Receiver

This document provides the technical specifications and characteristics for the M510 I/O bus receiver module. The M510 is a single-height module designed for PDP-15 I/O bus systems, featuring eight receiver circuits. Each circuit utilizes a two-stage emitter follower with TTL output buffers to provide both inverted and non-inverted outputs. The module is pin-compatible with the M500 series and is designed to improve signal integrity by offering high input impedance to reduce loading and noise issues.
