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

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
