Description
The PS391/ PS392/ PS393 are improved, quad, single-pole single-
throw (SPST) analog switches designed to operate with ±3V to ±8V
power supplies or a single 3V to 15V supply. The PS391 has four
normally closed (NC) switches, the PS392 has four normally open
(NO) switches. The PS393 has two NO and two NC switches. All
three devices offer low leakage (<2pA typ) and fast switching
speeds (t_ON <130ns). Power consumption is less than 1µA, ideal for
battery-powered equipment.
With ±5V supplies, the PS391/PS392/PS393 guarantee <2ohm
channel-to-channel matching, <30ohm on-resistance (R_ON), and
<4ohm R_ON flatness over the specified range.
These switches are fully specified for single +5V operation, with
<2ohm R_ON match, <45ohm R_ON, and <4ohm flatness.
For operation below 5V, the PI5A391A/PI5A392A/PI5A393A are
also recommended.
