DS3884A
DS3884A is BTL Handshake Transceiver manufactured by National Semiconductor.
Description
The DS3884A is one in a series of transceivers designed specifically for the implementation of high performance Futurebus+ and proprietary bus interfaces. The DS3884A is a BTL 6-bit Handshake Transceiver designed to conform to IEEE 1194.1 (Backplane Transceiver Logic
- BTL) as specified in the IEEE 896.2 Futurebus+ specification. n n n n n n n Glitch free power-up/down protection Typically less than 5 p F bus-port capacitance Low Bus-port voltage swing (typically 1V) at 80 m A TTL patible driver and control inputs Separate TTL I/O Open collector bus-port outputs allow Wired-OR connection Controlled rise and fall time to reduce noise coupling to adjacent lines Built in Bandgap reference with separate QV CC and QGND pins for precise receiver thresholds Exceeds 2 k V ESD testing (Human Body Model) Individual Bus-port ground pins Product offered in PQFP package styles
Features
Fast propagation delay (3 ns typ) 6-bit BTL transceiver Selective receiver glitch filtering (FR1- FR3) Meets 1194.1 Standard on Backplane Transceiver Logic (BTL) n Supports live insertion n n n n n n n n
