National Semiconductor AM290

This technology provides the industry's only low "ON" resistance, high speed, monolithic N-channel junction FET analog switch. The switch can block 20V peak-to-peak signals, and because of the driver design, an "OFF" isolation greater than 60 dB is achieved at 10 MHz.

GENERAL DESCRIPTION

These devices combine N-channel junction FETs and bipolar transistors on a single chip for the first time in a new N-channel Bi-FET process. Unique circuit techniques are employed to achieve break-before-make switching action and constant "ON" resistance over the analog voltage range.

FEATURES

Interfaces with standard DTL, TTL and CMOS Constant "ON" resistance with signals to i10V 00 "ON" resistance match 2 i~l typ "OFF" isolation and crosstalk less than —60 dB at 10 MHz (typ) tON'tOFF = 105 ns/95 ns typ 00 Break-before-make action Ol
