The data 0 2 60 (typ.) at V - V = 9.0 V CC EE at the select inputs may be latched by using the active Logic level translation: to enable 5 V logic to LOW latch enable input (LE). When LE is HIGH the latch communicate with 5 V analog signals is transparent. When either of the two enable inputs, E (active LOW) and E (active HIGH), is inactive, all 8 1 2 Typical break before make built in analog switches are turned off. Address latches provided V and GND are the supply voltage pins for the digital CC Output capability: non-standard control inputs (S to S , LE, E and E ). The V to GND 0 2 1 2 CC I category: MSI CC ranges are 2.0 to 10.0 V for HC and 4.5 to 5.5 V for HCT. The analog inputs/outputs (Y to Y , and Z) can swing 0 7 between V as a positive limit and V as a negative CC EE GENERAL DESCRIPTION limit. The 74HC/HCT4351 are high-speed Si-gate CMOS V - V may not exceed 10.0 V. CC EE devices. They are specified in compliance with JEDEC standard no. 7A. For operation as a digital multiplexer/demultiplexer, V is EE connected to GND (typically ground).
