309-509 T|e RS2376 Keyboard Encoder l.
C.
is a fully integrated P-MOS keyswitch encoding circuit, suitable for encoding a keyboard with up to 88 switches, plus shift and control, into a useable9 bit data code, i.
e.
the standard8 bit ASC ll datacode + one parity bit.
The RS2376offers the facilities of two key roll-over operation with N-key lockout and has userselectableodd or even parity and output polarity.
A self contained oscillator and debouncecircuit are incorporated in the device, requiring only the addition of a resistor and capacitor for each function.
The outputs are directly TTL/MOS logic compatible.
The RS 76 key Keyboard (336-703)is ...
