General description
The NX3L1T3157 provides one low-ohmic single-pole double-throw analog switch, suitable for use as an analog or digital multiplexer/demultiplexer. It has a digital select input (S) with Schmitt trigger action, two independent inputs/outputs (Y0, Y1) and a common input/output (Z).
Schmitt trigger action at the select input (S) makes the circuit tolerant to slower input rise and fall times across the entire VCC range from 1.4 V to 3.6 V.
Features
◾ Wide supply voltage range from 1.4 V to 3.6 V
◾ Very low ON resistance (peak):
✦ 1.6 Ω (typical) at VCC = 1.4 V
✦ 1.0 Ω (typical) at VCC = 1.65 V
✦ 0.55 Ω (typical) at VCC = 2.3 V
✦ 0.50 Ω (typical) at VCC = 2.7 V
◾ Break-before-make switching
◾ High noise immunity
◾ ESD protection:
✦ HBM JESD22-A114E Class 3A exceeds 7500 V
✦ MM JESD22-A115-A exceeds 200 V
✦ CDM AEC-Q100-011 revision B exceeds 1000 V
◾ CMOS low-power consumption
◾ Latch-up performance exceeds 100 mA per JESD 78 Class II Level A
◾ Direct interface with TTL levels at 3.0 V
◾ Control input accepts voltages above supply voltage
◾ Very low supply current, even when input is below VCC
◾ High current handling capability (350 mA continuous current under 3.3 V supply)
◾ Specified from −40 °C to +85 °C and from −40 °C to +125 °C
Applications
◾ Cell phone
◾ PDA
