Single SPST Analog Switch
The NLAST4501 is an analog switch manufactured in sub−micron
silicon−gate CMOS technology. It achieves very low R
maintaining extremely low power dissipation. The device is a bilateral
switch suitable for switching either analog or digital signals, which may
vary from zero to full supply voltage.
The NLAST4501 is a low voltage, TTL (low threshold) compatible
device, pin for pin compatible with the MAX4501.
The Enable pin is compatible with standard TTL level outputs when
supply voltage is nominal 5.0 Volts. It is also over−voltage tolerant,
making it a very useful logic level translator.
