Product data sheet
1. General description
The 74HC4051; 74HCT4051 is a high-speed Si-gate CMOS device and is pin compatible
with Low-power Schottky TTL (LSTTL). The device is specified in compliance with JEDEC
standard no. 7A.
The 74HC4051; 74HCT4051 is an 8-channel analog multiplexer/demultiplexer with three
digital select inputs (S0 to S2), an active-LOW enable input (E), eight independent
inputs/outputs (Y0 to Y7) and a common input/output (Z). With E LOW, one of the eight
switches is selected (low impedance ON-state) by S0 to S2. With E HIGH, all switches are
in the high-impedance OFF-state, independent of S0 to S2.
V_CC and GND are the supply voltage pins for the digital control inputs (S0 to S2, and E).
The V_CC to GND ranges are 2.0 V to 10.0 V for 74HC4051 and 4.5 V to 5.5 V for
74HCT4051. The analog inputs/outputs (Y0 to Y7, 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).
2. Features and benefits
 Wide analog input voltage range from 5 V to +5 V
 Low ON resistance:
 80  (typical) at V_CC  V_EE = 4.5 V
 70  (typical) at V_CC  V_EE = 6.0 V
 60  (typical) 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
 ESD protection:
 HBM JESD22-A114F exceeds 2000 V
 MM JESD22-A115-A exceeds 200 V
 CDM JESD22-C101E exceeds 1000 V
