description

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:

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.

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.
