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
ABT18502A , the binary value 00010000000000000110000000101111 (10000602F, hex) is captured
(during Capture-DR state) in the IDR to identify this device as Texas Instruments SN54/74ABT18502A.
For the
ABT182502A , the binary value 00000000000000010111000000101111 (0001702F, hex) is captured
(during Capture-DR state) in the IDR to identify this device as Texas Instruments SN54/74ABT182502A.
The IDR order of scan is from TDI through bits 31–0 to TDO. Table 2 shows the IDR bits and their significance.
