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 ’LVTH18502A, the binary value 00110000000000011100000000101111 (3001C02F, hex) is captured
(during Capture-DR state) in the IDR to identify this device as Texas Instruments SN54/74LVTH18502A.
For the ’LVTH182502A, the binary value 00110000000000100001000000101111 (3002102F, hex) is captured
(during Capture-DR state) in the device-identification register to identify this device as Texas Instruments
SN54/74LVTH182502A.
The IDR order of scan is from TDI through bits 310 to TDO. Table 2 shows the IDR bits and their significance.
