The Le88241 Tracking Battery ABS (Automatic Battery Switching) VoicePort device implements a dual-channel telephone line interface by providing all the necessary voice interface functions from the high voltage subscriber line to the µP/DSP digital interface. The ABS device can operate from external battery supplies, or from supplies generated by the on chip switching regulator controllers. This device reduces system level cost, space, and power by achieving the highest level of voice integration possible. Designers benefit by having a simple, cost effective, low power and dense, interface design without sacrificing features or functionality. The programmable, feature rich VoicePort devices provide a highly functional line interface which meets the requirements of short and medium loop (up to 1500 Ohms total at 1 REN) applications. Features include: high voltage switching regulator, self-test, line test capabilities, integrated ringing (up to 110-Vpk), worldwide software programmability, flexible signal generator with tone cadencing, caller ID generation and all BORSCHT functions. These VoicePort device features are crucial for designing cost-effective, full-featured Voice over Broadband solutions.

8-Bit Dual-Supply Bus Transceiver with Configurable Voltage Translation and 3-State Outputs

The SN74LVC2G34 device is a dual buffer gate designed for 1.65-V to 5.5-V V CC operation. The SN74LVC2G34 device performs the Boolean function Y = A in positive logic. NanoFree package technology is a major breakthrough in IC packaging concepts, using the die as the package. This device is fully specified for partial-power-down applications using I off . The I off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
