Description
The PS4581 is an eight-channel, single-ended multiplexer designed
to select one of eight inputs to a common output. The input
selected depends on the status of three address bits (ADDA,ADDB,
andADDC). The PS4582 is a differential four-channel multiplexer,
controlled by two address bits:ADDAandADDB. The PS4583 is a
triple SPDT, single-pole, double-throw switch.
The INH (inhibit) pin is driven high to open all switches
regardless of address bit status. All control inputs are TTL
compatible with a single 5V or dual ±5V supply.
These devices are designed to operate with dual power supplies
from ±2V to ±6V. Single-supply operation is possible from
+2Vto+12V.
When on, each switch conducts current equally well in either
direction and can handle rail-to-rail analog signals. In the
off-state, each switch blocks voltages up to the power-supply
rails. Off-leakage current is guaranteed to be less than 7nA at
+25oC, or 50nA at +85oC
These devices are available in 16-pin DIP, SOIC, and QSOP
packages for operation over the 40oC to +85oC temperature range.
