CMOS Keyboard Encoder

Description The CDP1871A is a keyboard encoder designed to directly interface between a CDP1800-series microprocessor and a mechanical keyboard array, providing up to 53 ASCII coded keys and 32 HEX coded keys, as shown in the system diagram (Figure 1). Features • Directly Interfaces with CDP180

Integrated Circuit Module - Dual AF Power Amplifier, 50W/Ch, Dual Power Supplies

Features: • Built–In Muting Circuit to Cut–Off Pop Noise

1.8V, INPUT/OUTPUT RAIL TO RAIL LOW POWER OPERATIONAL AMPLIFIERS

Description The TS187x (single, dual and quad) is an operational amplifier family able to operate with voltages as low as 1.8V and that features both input and output rail-to-rail. Features ■ Operating range from VCC = 1.8V to 6V ■ Rail-to-rail input and output ■ Extended Vicm (VDD - 0.2
