The SN74ABT18640 is an 18-bit inverting bus transceiver integrated circuit designed for scan testing applications. It is part of the Texas Instruments SCOPE family, which supports IEEE Standard 1149.1-1990 for boundary-scan testing, facilitating the testing of complex circuit-board assemblies. The device can operate in normal mode as either two 9-bit transceivers or one 18-bit transceiver, with data flow controlled by direction-control and output-enable inputs. In test mode, the device's normal operation is inhibited, allowing the test circuitry to perform various functions such as parallel-signature analysis and pseudo-random pattern generation. The SN74ABT18640 is available in shrink small-outline (DL) and thin shrink small-outline (DGG) packages, providing a compact solution with a high I/O pin count. It operates within a temperature range of -40¬8C to 85¬8C and requires a supply voltage of 4.5V to 5.5V. This product is suitable for applications requiring robust testing capabilities in a space-efficient package.
