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 ’LVTH18514, the binary value 00000000000000111101000000101111 (0003D02F, hex) is captured
(during Capture-DR state) in the IDR to identify this device as TI SN54/74LVTH18514.
For the ’LVTH182514, the binary value 00000000000000111110000000101111 (0003E02F, hex) is captured
(during Capture-DR state) in the IDR to identify this device as TI SN54/74LVTH182514.
The IDR order of scan is from TDI through bits 31–0 to TDO. Table 2 shows the IDR bits and their significance.
