† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: Voltage values for maximum ratings are with respect to VBB.

The TCM29C13A, TCM29C14A, TCM29C16A, TCM29C17A, TCM129C13A, TCM129C14A, TCM129C16A, and TCM129C17A are single-chip PCM codecs (pulse-code-modulated encoders and decoders) and PCM line filters. These devices provide all the functions required to interface a full-duplex (4-wire) voice telephone circuit with a time-division-multiplexed (TDM) system. These devices are intended to replace the TCM2910A or TCM2911A in tandem with the TCM2912C. Primary applications include:

• Line interface for digital transmission and switching of T1 carrier, PABX, and central office telephone systems
• Subscriber line concentrators
• Digital-encryption systems
• Digital voice-band data storage systems
• Digital signal processing
