description
The TLC04/MF4A-50 and TLC14/MF4A-100 are monolithic Butterworth low-pass switched-capacitor filters.
Each is designed as a low-cost, easy-to-use device providing accurate fourth-order low-pass filter functions in
circuit design configurations.
Each filter features cutoff frequency stability that is dependent only on the external-clock frequency stability . The
cutoff frequency is clock tunable and has a clock-to-cutoff frequency ratio of 50:1 with less than ±0. 8% error
for the TLC04/MF4A-50 and a clock-to-cutoff frequency ratio of 100:1 with less than ±1% error for the
TLC14/MF4A-100. The input clock features self-clocking or TTL- or CMOS-compatible options in conjunction
with the level shift (LS) terminal.
The TLC04C/MF4A-50C and TLC14C/MF4A-100C are characterized for operation from 0°C to 70°C. The
TLC04I/MF4A-50I and TLC14I/MF4A-100I are characterized for operation from –40°C to 85°C. The
TLC04M/MF4A-50M and TLC14M/MF4A-100M are characterized over the full military temperature range of
–55°C to 125°C.

DESCRIPTION
AGND 6 I Analog ground. The noninverting input to the operational amplifiers of the Butterworth fourth-order low-pass filter .
CLKIN 1 I Clock in. CLKIN is the clock input terminal for CMOS-compatible clock or self-clocking options. For either option,
LS is at VCC–. For self-clocking, a resistor is connected between CLKIN and CLKR and a capacitor is connected
from CLKIN to ground.
CLKR 2 I Clock R. CLKR is the clock input for a TTL-compatible clock. For a TTL clock, LS is connected to midsupply and
CLKIN can be left open, but it is recommended that it be connected to either VCC+ or VCC–.
FILTER IN 8 I Filter input
FILTER OUT 5 O Butterworth fourth-order low-pass filter output
LS 3 I Level shift. LS accommodates the various input clocking options. For CMOS-compatible clocks or self-clocking,
LS is at VCC– and for TTL-compatible clocks, LS is at midsupply.
VCC+ 7 I Positive supply voltage terminal
VCC– 4 I Negative supply voltage terminal
