AM3705
AM3705 is 8-Channel MOS Analog Multiplexer manufactured by National Semiconductor.
Description
The AM3705/AM3705C is an eight-channel MOS analog multiplex switch. TTL patible logic inputs that require no level shifting or input pull-up resistors and operation over a wide range of supply voltages is obtained by constructing the device with low threshold P-channel enhancement
MOS technology. To simplify external logic re- quirements, a one-of-eight decoder and an output enable are included in the device.
Important design features include:
TTL/DTL patible input logic levels Operation from standard +5V and -1 5V supplies Wide analog voltage range
- ±5V One of eight decoder on chip
Output enable control
Low ON resistance
- 15012
Input gate protection
Low leakage currents
- 0.5 n A
The AM3705/AM3705C is designed as a low cost analog multiplex switch to fulfill a wide variety of data acquisition and data distribution applications
MUX including cross-point switching, front ends for A/D converters, process controllers, automatic test gear, programmable power supplies and other military or industrial instrumentation applications.
The AM3705 is specified for operation over the
-55°C to +125°C military temperature range. The AM3705C is specified for operation over the -25 C to +85°C temperature range.
