The LSTTL input compatibility is provided by an input integrated circuit, with industry standard logic levels. This input amplifier IC switches a temperature compensated current source driving a high speed 850nm AlGaAs LED emitter. This novel integration scheme eliminates CTR degradation over time and temperature.
1. Industry first LSTTL to TTL and LSTTL to CMOS complete logic-to-logic optocoupler 2. Incorporates LED drive circuitry — use as a logic gate 3. Very high speed 4. Choice of buffer or inverter 5. Choice of TTL or CMOS compatible output up to 15 volts
The PALCE16V8 is an advanced PALdevice built with low-power, high-speed, electricallyerasable CMOS technology. It is functionally compatible with all 20-pin GAL devices. The macrocells provide a universal device architecture. The PALCE16V8 will directly replace the PAL16R8, with the exception of the PAL16C1. The fixed OR array allows up to eight data product terms per output for logic functions. The sum of these products feeds the output macrocell. Each macrocell can be programmed as registered or combinatorial with an active-high or active-low output. The output configuration is determined by two global bits and one local bit controlling four multiplexers in each macrocell.
1. Pin and function compatible with all 20-pin PAL devices 2. Electrically erasable CMOS technology provides reconfigurable logic and full testability 3. High-speed CMOS technology (1) 5-ns propagation delay for “-5” version (2) 7.5-ns propagation delay for “-7” version 4. Direct plug-in replacement for the PAL16R8 series 5. Outputs programmable as registered or combinatorial in any combination
