december 1990 2 philips semiconductors product speci?cation 8-channel analog multiplexer/demultiplexer with latch 74hc/hct4351 features wide analog input voltage range: 5 v low on resistance: 80 w (typ.) at v cc - v ee = 4.5 v 70 w (typ.) at v cc - v ee = 6.0 v 60 w (typ.) at v cc - v ee = 9.0 v logic level translation: to enable 5 v logic to communicate with 5 v analog signals typical break before make built in address latches provided output capability: non-standard i cc category: msi general description the 74hc/hct4351 are high-speed si-gate cmos devices. they are specified in compliance with jedec standard no. 7a. the 74hc/hct4351 are 8-channel analog multiplexers/demultiplexers with three select inputs (s 0 to s 2 ), two enable inputs ( e 1 and e 2 ), a latch enable input ( le), eight independent inputs/outputs (y 0 to y 7 ) and a common input/output (z). with e 1 low and e 2 is high, one of the eight switches is selected (low impedance on-state) by s 0 to s 2 . 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 8 analog switches are turned off. v cc and gnd are the supply voltage pins for the digital control inputs (s 0 to s 2 , le, e 1 and e 2 ). the v cc to gnd ranges are 2.0 to 10.0 v for hc and 4.5 to 5.5 v for hct. the analog inputs/outputs (y 0 to y 7 , and z) can swing between v cc as a positive limit and v ee as a negative limit. v cc - v ee may not exceed 10.0 v. for operation as a digital multiplexer/demultiplexer, v ee is connected to gnd (typically ground). quick reference data v ee = gnd = 0 v;
