device-identification register
The device-identification register (IDR) is 32 bits long. It can be selected and read to identify the manufacturer,
part number, and version of this device.
For the ’LVTH18504A, either of the binary values 00100000000000011101000000101111 (2001D02F, hex) or
00110000000000011101000000101111 (3001D02F, hex) is captured (during Capture-DR state) in the IDR to
identify this device as TI SN54/74LVTH18504A.
For the ’LVTH182504A, either of the binary values 00010000000000100010000000101111 (1002202F, hex)
or 00100000000000100010000000101111 (2002202F, hex) is captured (during Capture-DR state) in the IDR
to identify this device as TI SN54/74LVTH182504A.
The IDR order of scan is from TDI through bits 31–0 to TDO. Table 2 shows the IDR bits and their significance.

Note that for TI products, bits 11–0 of the device-identification register always contain the binary value 000000101111
(02F, hex).
