74HC/HCT433 FEATURES Wide analog input voltage range: ± V Low ON resistance: 8 (typ.) at = V 7 (typ.) at = 6. V 6 (typ.) at = 9. V Logic level translation: to enable V logic to communicate with ± V analog signals Typical break befe make built in Address latches provided Output capability: non-standard I CC categy: MSI GENERAL DESCRIPTION The 74HC/HCT433 are high-speed Si-gate CMOS devices. They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT433 are triple 2-channel analog multiplexers/demultiplexers with two common enable inputs (E 1 and E 2 ) and a latch enable input (LE). Each multiplexer has two independent inputs/outputs (ny and ny 1 ), a common input/output (nz) and select inputs (S 1 to S 3 ). Each multiplexer/demultiplexer contains two bidirectional analog switches, each with one side connected to an independent input/output (ny and ny 1 ) and the other side connected to a common input/output (nz). With E 1 LOW and E 2 HIGH, one of the two switches is selected (low impedance ON-state) by S 1 to S 3. The data at the select inputs may be latched by using the active LOW latch enable input (LE). When LE is HIGH, the latch is transparent. When either of the two enable inputs, E 1 (active LOW) and E 2 (active HIGH), is inactive, all analog switches are turned off. and GND are the supply voltage pins f the digital control inputs (S 1 to S 3, LE, E 1 and E 2 ). The to GND ranges are 2. to 1. V f HC and to. V f HCT. The analog inputs/outputs (ny and ny 1, and nz) can swing between as a positive limit and as a negative limit. may not exceed 1. V. F operation as a digital multiplexer/demultiplexer, is connected to GND (typically ground).

To avoid drawing current out of terminals nz, when switch current flows in terminals ny n, the voltage drop across the bidirectional switch must not exceed.4 V. If the switch current flows into terminals nz, no current will flow out of terminals ny n. In this case there is no limit f the voltage drop across the switch, but the voltages at ny n and nz may not exceed.
