data lssuedNovember1984 4080 Keyboardencoder i.c.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 designedto accept the RS2376KeyboardEncoderLC.
