The Abaco Systems IP-TTL48-8 is a 48-channel TTL digital I/O IndustryPack module engineered for flexible input/output applications requiring individual line control and synchronized buffering. Built on six 74HCT652 transceiver chips, this single-wide module delivers 48 independently configurable TTL lines with double-buffered input and output capability—essential for simulation systems that demand simultaneous latching across multiple channels.
