Pin-compatible upgrades for 74HC4051/4052/4053
Description
The PS4051/PS4052/PS4053 are precision low-voltage CMOS
analog multiplexers/switches.
The PS4051 is an eight-channel single-ended mux designed to
select one of eight inputs to a common output. What input is
selected depends on the status of three address bits (ADDA-ADDC).
The PS4052 is a differential four-channel mux, controlled by two
address bits: ADDA, and ADDB. The PS4053 is a triple 2-to-1
mux (or triple SPDT, single-pole double-throw, switch).
The INH (inhibit) pin can be driven high, to open all switches
regardless of address bit status. All control inputs are TTL
compatible when V+ = +5V.
These devices are designed to operate with power supplies
from 鹵2.7V to 鹵8V. Single-supply operation is possible from
+2.7V to +16V.
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 0.1nA at +25
o
C,
and < 2.5nA at +85
o
C.
These devices are available in 16-pin DIP, Narrow SOIC, and QSOP
packages for operation over the 聳40
o
C to +85
o
C temperature range.
