描述 Description

CD4067B and CD4097B CMOS analog multiplexers/demultiplexers* are digitally controlled analog switches having low ON impedance, low OFF leakage current, and internal address decoding. In addition, the ON resistance is relatively constant over the full input-signal range. The CD4067B is a 16-channel multiplexer with four binary control inputs, A, B, C, D, and an inhibit input, arranged so that any combination of the inputs selects one switch.

The CD4097B is a differential 8-channel multiplexer having three binary control inputs, A, B, C, and an inhibit input. The inputs permit selection of one of eight pairs of switches.

A logic \"1\" present at the inhibit input turns all channels off.

The CD4067B and CD4097B types are supplied in 24-lead hermetic dual-in-line ceramic packages (F3A suffix), 24-lead dual-in-line plastic packages (E suffix), 24-lead small-outline packages (M, M96, and NSR suffixes), and 24-lead thin shrink small-outline packages (P and PWR suffixes).

特性 Features

? Low ON resistance: 125 (typ.) over 15 Vp-p signal-input range for VDD - VSS = 15 V
? Matched switch characteristics: RON = 5 (typ.) for VDD - VSS = 15 V
? Binary address decoding on chip
? 100% tested for quiescent current at 20 V
? Meets all requirements of JEDEC Tentative Standard No. 13A, \"Standard Specifications for Description of 'B' Series CMOS Devices\"
? Analog and digital multiplexing and demultiplexing
? Siganl gating

* When these devices are used as demultiplexers, the channel in/out terminals are the outputs and the common out/in terminals are the inputs.
