description
The TLC552 is a dual monolithic timing circuit
fabricated using TI LinCMOS
process, which
provides full compatibility with CMOS, TTL, and
MOS logic and operation at frequencies up to
2 MHz. Accurate time delays and oscillations are
possible with smaller, less-expensive timing
capacitors than the NE555 because of the high
input impedance. Power consumption is low
across the full range of power supply voltages.
Like the NE556, the TLC552 has a trigger level
approximately one-third of the supply voltage and
a threshold level approximately two-thirds of the
supply voltage. These levels can be altered by use
of the control voltage terminal. When the trigger
input falls below the trigger level, the flip-flop is set
and the output goes high. If the trigger input is
above the trigger level and the threshold input is
above the threshold level, the flip-flop is reset and
the output is low. The reset input can override all other inputs and can be used to initiate a new
timing cycle. If the reset input is low, the flip-flop is reset and the output is low. Whenever the output is low, a
low-impedance path is provided between the discharge terminal and ground.
While the CMOS output is capable of sinking over 100 mA and sourcing over 10 mA, the TLC552 exhibits greatly
reduced supply-current spikes during output transitions. This minimizes the need for the large decoupling
capacitors required by the NE556.
