Typical Performance Characteristics
Typical Irp vs VIN at Any Y Input
Typical Ron vs VOUT at Any X Output
Typical FSCAN vs COSC
Typical Debounce Period vs CKBM
Typical Applications
Synchronous Handshake (MM74C922)
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
Synchronous Data Entry Onto Bus (MM74C922)
Outputs are enabled when valid entry is made and go into 3-STATE when
key is released.
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
