Low-Voltage, 8-Channel/Dual 4-Channel

Multiplexers with Latchable Inputs

_______________General Description

The MAX382/MAX384 are low-voltage, CMOS, 1-of-8 and dual 4-channel muxes with latchable digital inputs. They feature low-voltage operation from a +2.7V to +16.5V single supply and from ±3V to ±8V dual supplies. Pin compatible with the DG428/DG429, these muxes offer low on-resistance (100Ω max) matched to within 4Ω max between channels. Additional features include off leakage less than 2.5nA at +85°C and guaranteed low charge injection (10pC max). ESD protection is greater than 2000V per Method 3015.7.

____________________________Features

♦ Pin-Compatible with Industry-Standard

DG428/DG429, DG528/DG529, MAX368/MAX369

♦ Single-Supply Operation (+2.7V to +16.5V)

Bipolar Supply Operation (±3V to ±8V)

♦ Low Power Consumption (<300µW) ♦ Low On-Resistance, 100Ω max ♦ Guaranteed On-Resistance Match Between

Channels, 4Ω max

♦ Low Leakage, 2.5nA at +85°C ♦ TTL/CMOS-Logic Compatible

Note 1: Signals on any terminal exceeding V+ or V- are clamped by internal diodes. Limit forward current to maximum current ratings.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
