SN74LVTH182502A

The Texas Instruments SN74LVTH182502A is a high-speed, 18-bit universal bus transceiver featuring Advanced BiCMOS Technology (ABT). This device is part of the SCOPE family of testability products and the Widebus family, offering state-of-the-art performance for 3.3-V systems.

Key electrical characteristics include 18 channels, TTL-compatible CMOS inputs, and 3-state outputs. It supports mixed-mode signal operation, allowing 5-V input and output voltages with a 3.3-V VCC, and can operate with unregulated battery power down to 2.7 V. The transceiver combines D-type latches and D-type flip-flops for flexible operation in transparent, latched, or clocked modes.

Features such as bus hold on data inputs eliminate the need for external pullup resistors. The B-port outputs include equivalent 25- series resistors, simplifying external component requirements. The device is compatible with the IEEE Standard 1149.1-1990 (JTAG) test access port and boundary-scan architecture, supporting various SCOPE instruction sets for enhanced testability.

Packaged in a 64-pin LQFP (PM) measuring 12 mm x 12 mm with 0.5-mm spacing, and also available in a 68-pin Ceramic Quad Flat (HV) package with 25-mil spacing. The operating temperature range is -40°C to 85°C.
