_________________General Description
The MAX4536/MAX4537/MAX4538 are quad, low-voltage,
single-pole/single-throw (SPST) analog switches with a
common enable pin. They are pin compatible with the
industry-standard 74HC4316. The MAX4536 has four
normally open (NO) switches, and the MAX4537 has
four normally closed (NC) switches. The MAX4538 has
two NO switches and two NC switches.
These switches operate from a +2V to +12V single supply,
or from ±2V to ±6V dual supplies. On-resistance
(200
max) is matched between switches to 4
(max)
and is flat (10
max) over the specified signal range.
Each switch can handle rail-to-rail analog signals. The
off-leakage current is only 1nA at +25°C and 10nA at
+85°C.
All digital inputs have 0.8V to 2.4V logic thresholds,
ensuring TTL/CMOS-logic compatibility when using a
single +5V supply or dual ±5V supplies.
