3.3 -V ABT扫描测试了18位通用总线收发器器件 3.3-V ABT SCAN TEST DEVICES WITH 18-BIT UNIVERSAL BUS TRANSCEIVERS
description
The ’LVT18512 and ’LVT182512 scan test devices with 18-bit universal bus transceivers are members of the Texas Instruments SCOPE testability integrated-circuit family. This family of devices supports IEEE Std 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.
