PSB8510-1P

The PSB8510-1P is programmable dialing circuit. It is designed to implement dual tone multifrequency and pulse dialing in a telephone set. It can be connected directly to a standard push button keyboard with up to 16 buttons.

Features of the PSB8510-1P are:(1)advanced CMOS technology;(2)pulse and dual tone multi frequency dialing on the chip;(3)mixed dial and redial;(4)selection of default dial mode by selecting pins;(5)last number redial up to 22 digits with data retention moitoring;(6)generation of 12 different frequency pairs;(7)DTMF output signals meet CEPT specification without external filtering;(8)DTMF-level is independent of supply-voltage;(9)single tone generation;(10)no external components except TV standard crystal of ceramic resonator;(11)keyboard wake up function allows reduced power consumption;(12)automatic and/or manual access pause generation depending on the version;(13)special device control keys;(14)low data retention voltage;(15)low operation and standard current;(16)internal power-on reset.

The absolute maximum ratings of the PSB8510-1P can be summarized as:(1)DC supply voltage:-0.5V to 28V;(2)input voltage at any pin:(VSS-0.5)V to (VDD+0.5)V;(3)power dissipation:500mW;(4)operating ambient temperature:-25 to +70;(5)storage temperature:-55 to +125.
