SN54LVTH18502A 具有 18 位通用总线收发器的 3.3V ABT 扫描测试设备

The ’LVTH18502A and ’LVTH182502A scan test devices with 18-bit universal bus transceivers are members of the Texas Instruments SCOPETM testability integrated-circuit family. This family of devices supports IEEE Standard 1149.1-1990 boundary scan to facilitate testing of complex circuit-board assemblies. Scan access to the test circuitry is accomplished via the 4-wire test access port (TAP) interface.

Additionally, these devices are designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

In the normal mode, these devices are 18-bit universal bus transceivers, that combine with D-type latches and D-type flip-flops, they allow data to flow in the transparent, latched, or clocked modes
