HT93214AT Product details

General Description
The HT93214 are dialer series designed for low cost telephone set applications with expandable features such as Lock function, keytone and LCD display interface. With a 44 keyboard, it performs normal tone/pulse switchable dialing, and provides one-key redialing function with a 32-digit memory for speed dialing. An on-chip oscillator is built-in to work with an exter nal 3.58Mhz crystal or ceramic resonator for accurate timing. The HT93214 provides 300ms (F1 key) and 600ms (F2 key) of flash time; Tone dialing and 10pps, 20pps selection with 1/2 M/B ratio for pulse dialing.
