Part Number : DG301
Function : Quad, TTL compatible CMOS analog switch.
Package : 10 Lead Metal Can Type, DIP 14 Pin type
Maker : Maxim Integrated
Pinouts : 
Description :
Maxim’s DG300, DG301 and DG300A, DG303A CMOS dual and quad analog switches combine low power operation with fast switching times and superior DC and AC switch characteristics.
On-resistance is less than 50Ohm and is essentially constant over the analog signal range. Device specifications are ideal for battery powered circuitry.
Applications :
1. Portable Instruments
2. Low-Power Sample/Holds
3. Power-Supply Switching
4. Programmable Gain Amplifiers
5. SPDT and DPDT Functions
6. Process Control and Telemetry
