Product speciﬁcation

Pulse and DTMF diallers with redial

PCD3310; PCD3310A

Notes

1. Crystal connected between OSCI and OSCO; CE at VSS and all other pins open-circuit.

2. <

10 mA dynamic current to set/reset PD/DTMF pin (mixed mode).

3. Flash inactive; output voltage = VSS.

4. Related to the level of the LOW group frequency component, according to CEPT recommendations.
