General Description

The LVT16952 and LVTH16952 are 16-bit registered transceivers. Two 8-bit back to back registers store data flowing in both directions between two bidirectional buses. Separate clock, clock enable, and output enable signals are provided for each register.

The LVTH16952 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.

The registered transceiver is designed for low-voltage (3.3V) VCC applications, but with the capability to provide a TTL interface to a 5V environment.

The LVT16952 and LVTH16952 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining low power dissipation.
