Ex R&D spare parts
I am currently working through a spare parts drawer (from my previous business) of weird and wonderful special purpose chips, this is one of those.
While not likely to be used in the service environment these days, this chip has interesting functions if someone wished to investigate further.
NATIONAL SEMICONDUCTOR - PCM Codec & Filter
Type: TP3057J
Serial interface Codec/Filter combo
Designed for D3D4 & CCITT applications
Low power consumption (CMOS)
If you are thirsty for more details, HERE is a link to the datasheet
16 pin DIL Plastic
NEW Old Stock
Another chip that has been in the spare parts drawers for yonks! I can see the legs remain quite 'shiny' and of course, straight ... this chip should still be perfectly serviceable.
This will be supplied exactly as it was stored, on a bed of ESD foam and within a sealed clear plastic packet.
