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 ’LVTH18640, the binary value 00000000000000110000000000101111 (0003002F, hex) is captured
(during Capture-DR state) in the device-identification register to identify this device as Texas Instruments
SN54/74LVTH18640.
For the ’LVTH182640, the binary value 00000000000000110001000000101111 (0003102F, hex) is captured
(during Capture-DR state) in the device-identification register to identify this device as Texas Instruments
SN54/74LVTH182640.
The IDR order of scan is from TDI through bits 31–0 to TDO. Table 2 shows the IDR bits and their significance.
