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 ’ABTH18646A , the binary value 00000000000000101001000000101111 (0002902F, hex) is captured
(during Capture-DR state) in the IDR to identify this device as Texas Instruments SN54/74ABTH18646A.
For the ’ABTH182646A , the binary value 00000000000000101101000000101111 (0002D02F, hex) is captured
(during Capture-DR state) in the IDR to identify this device as Texas Instruments SN54/74ABTH182646A.
The IDR order of scan is from TDI through bits 31–0 to TDO. Table 2 shows the IDR bits and their significance.
