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 ’ABTH18652A , the binary value 00000000000000101010000000101111 (0002A02F, hex) is captured
(during Capture-DR state) in the IDR to identify this device as Texas Instruments SN54/74ABTH18652A.
For the ’ABTH182652A , the binary value 00000000000000101110000000101111 (0002E02F, hex) is captured
(during Capture-DR state) in the IDR to identify this device as Texas Instruments SN54/74ABTH182652A.
The IDR order of scan is from TDI through bits 31–0 to TDO. Table 2 shows the IDR bits and their significance.
