74HC4067; 74HCT4067 16-channel analog multiplexer/demultiplexer Rev. 03 — 15 October 2007 Product data sheet 1. General description The 74HC4067; 74HCT4067 is a high-speed Si-gate CMOS device and is pin compatible with the HEF4067B. The device is specied in compliance with JEDEC standard no. 7A. The 74HC4067; 74HCT4067 is a 16-channel analog multiplexer/demultiplexer with four address inputs (S0 to S3), an active-LOW enable input (E), sixteen independent inputs/outputs (Y0 to Y15) and a common input/output (Z). The 74HC4067; 74HCT4067 contains sixteen bidirectional analog switches, each with one side connected to an independent input/output (Y0 to Y15) and the other side connected to a common input/output (Z). With pin E = LOW, one of the sixteen switches is selected by pins S0 to S3 (low impedance ON-state). All unselected switches are in the high-impedance OFF-state. With pin E = HIGH, all switches are in the high-impedance OFF-state, independent of pins S0 to S3. The analog inputs/outputs (Y0 to Y15, and Z) can swing between VCC as a positive limit and GND as a negative limit. VCC to GND may not exceed 10 V. 2. Features I Low ON resistance: N 80 (typical) at VCC = 4.5 V N 70 (typical) at VCC = 6.0 V N 60 (typical) at VCC = 9.0 V I Typical ‘break before make’ built-in 3. Applications I Analog multiplexing and demultiplexing I Digital multiplexing and demultiplexing I Signal gating NXP Semiconductors 74HC4067; 74HCT4067 16-channel analog multiplexer/demultiplexer 4……
