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.
♦ Pin Compatible with 74HC4316
♦ ±2.0V to ±6V Dual Supplies
+2.0V to +12V Single Supply
♦ Four Separately Controlled SPST Switches
with Common Enable
♦ 100Ω Signal Paths with Dual ±5V Supplies
200Ω Signal Paths with Single +4.5V Supply
♦ Rail-to-Rail Signal Handling
These switches operate from a +2V to +12V single supply,
or from ± 2V to ± 6V d ua l s up p lie s . On-re s is ta nc e
(200Ω max) is matched between switches to 4Ω (max)
and is flat (10Ω 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.
♦ t
and t
= 100ns and 80ns at ±4.5V Supply

OFF
♦ Less than 1µW Power Consumption
♦ >2kV ESD Protection per Method 3015.7
♦ TTL/CMOS-Compatible Inputs
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.
♦ Small Packages: PDIP, QSOP, Narrow SO
