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 inter-
face. With a 4 4 keyboard, it performs normal
tone/pulse switchable dialing, and provides one-key
redialing function with a 32-digit memory for speed dial-
ing. 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.
