description (continued)
Four dedicated test pins are used to 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.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The B-port outputs of ’LVTH182504A, which are designed to source or sink up to 12 mA, include equivalent 25-
series resistors to reduce overshoot and undershoot.
The SN54LVTH18504A and SN54LVTH182504A are characterized for operation over the full military
temperature range of –55
°C to 125°C. The SN74LVTH18504A and SN74LVTH182504A are characterized for
operation from –40
°C to 85°C.
