POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description (continued)
Four dedicated test pins observe and control the operation of the test circuitry: test-data input (TDI), test-data
output (TDO), test-mode select (TMS), and test clock (TCK). Additionally, the test circuitry performs other testing
functions such as parallel-signature analysis (PSA) on data inputs and pseudo-random pattern generation
(PRPG) from data outputs. All testing and scan operations are synchronized to the TAP interface.
The SN54ABT18245A is characterized for operation over the full military temperature range of –55
°C to 125°C.
The SN74ABT18245A is characterized for operation from –40
°C to 85°C.
