Synchronous Data Entry Onto Bus (MM74C922)
TL/F/6037–11
Outputs are enabled when valid entry is made and
go into TRI-STATE when key is released.
Note 3:
The keyboard may be synchronously scanned by omitting the capacitor at osc. and driving osc. directly if the system clock rate is lower than 10 kHz.
