MM450/MM550, MM451/MM551 MM452/MM552, MM455/MM555 MOS analog switches
general description
The MM450, and MM550 series each contain four p channel MOS enhancement mode transistors built on a single monolithic chip. The four transistors are arranged as follows:
MM450, MM550 MM451, MM551 MM452, MM552 MM455, MM555
Dual Differential Switch Four Channel Switch Four MOS Transistor Package Three MOS Transistor Package
These devices are useful in many airborne and
ground support systems requiring multiplexing,
analog transmission, and numerous signal routing
applications. The use of low threshold transistors
(VTH = 2 volts) permits operations with large ana-
log input swings (± 10 volts) at low gate voltages (~20 volts). Significant features, then, include:'
• Large Analog Input Swing
±10 Volts
• Low Supply Voltage
V BU LK = +10 Volts
VGG = ~20 Volts
• Low ON Resistance VIN = -10V
150>2
+10V
75>2
• Low Leakage Current
200 pA@25°C
• Input Gate Prote.
