Philips Semiconductors Product specification
Quad bilateral switches 74HC/HCT4316
FEATURES
•Low “ON” resistance:
160 Ω(typ.) at VCC −VEE = 4.5 V
120 Ω(typ.) at VCC −VEE = 6.0 V
80 Ω(typ.) at VCC −VEE = 9.0 V
•Logic level translation:
to enable 5 V logic to communicate
with ±5 V analog signals
•Typical “break before make” built in
•Output capability: non-standard
•ICC category: MSI
GENERAL DESCRIPTION
The 74HC/HCT4316 are high-speed Si-gate CMOS
devices. They are specified in compliance with JEDEC
standard no. 7A.
The 74HC/HCT4316 have four independent analog
switches. Each switch has two input/output terminals
(nY, nZ) and an active HIGH select input (nS). When the
enable input (E) is HIGH, all four analog switches are
turned off.
Current through a switch will not cause additional VCC
current provided the voltage at the terminals of the switch
is maintained within the supply voltage range;
VCC >> (VY, VZ)>> VEE. Inputs nY and nZ are electrically
equivalent terminals.
VCC and GND are the supply voltage pins for the digital
control inputs (E and nS). The VCC 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 (nY and nZ) can swing between
VCC as a positive limit and VEE as a negative limit.
VCC −VEE may not exceed 10.0 V.
See the “4016” for the version without logic level
translation.

Notes
1. CPD is used to determine the dynamic power
dissipation (PD in µW):
PD=C
PD ×VCC2×fi+∑{(C
L+C
S
)×V
CC2×fo}
where:
fi= input frequency in MHz
fo= output frequency in MHz
∑ {(C
L+C
S
)×V
CC2×fo} = sum of outputs
CL= output load capacitance in pF
CS= max. switch capacitance in pF
VCC = supply voltage in V
2. For HC the condition is VI= GND to VCC
For HCT the condition is VI= GND to VCC −1.5 V
