8-Channel/Differential 4-Channel, CMOS
High Speed Analog Multiplexer

The Hl-518 is a monolithic, dielectrically isolated, high
speed, high performance CMOS analog multiplexer. It offers
unique built-in channel selection decoding plus an inhibit
input for disabling all channels.Thedualfunctionof address
input A

enables the Hl-518 to be user programmed either

2

as a single ended 8-Channel multiplexer by connecting ‘Out
A’ to ‘Out B’ and using A
4-Channel differential multiplexer by connecting A

as a digital address input, or as a

2

to the V-

2

supply. The substrate leakages and parasitic capacitances
are reduced substantially by using the Intersil Dielectric
Isolation process to achieve optimum performance in both
high and low level signal applications. The low output
leakage current (l
(t

SETTLE

= 800ns to 0.01%) characteristics of the device

< 100pA at 25oC) and fast settling

D(OFF)

make it an ideal choice for high speed data acquisition
systems, precision instrumentation, and industrial process
control.
