3 Description
The TLC3555-Q1 is a monolithic timing circuit
fabricated using a TI CMOS process. The timer is
fully compatible with CMOS, TTL, and MOS logic
and operates at frequencies to 3MHz and even
beyond. The TLC3555-Q1 improves upon the existing
TLC555-Q1 from both a performance and feature
standpoint, with tighter specification tolerances and
additional features, such as thermal shutdown and
power-on reset.
The trigger, threshold, and reset logic of the TLC3555-
Q1 follow the same truth table as the TLC555-Q1. Set
the reset pin (RESET) high for typical operation, or
set the reset pin low to reset the flip-flop and force
the output low. The TLC3555-Q1 features an internal
pullup resistor from RESET to VDD, which can reduce
passive count and save board area.
As a result of low propagation delay and rapid
rise and fall times, the TLC3555-Q1 supports higherfrequency
astable operation than previous timers such
as the NE555 and TLC555-Q1. At a 15V supply,
the TLC3555-Q1 achieves a clean square wave at
3.1MHz in TI's conventional astable test circuit. When
used as an oscillator, with the output and inputs
tied together, the TLC3555-Q1 achieves an oscillatory
frequency of 7.2MHz. Circuit parasitics dominate the
response at high frequencies. In addition to the
D package, which is pin-to-pin compatible with the
TLC555-Q1, the TLC3555-Q1 is offered in a DDF
package that enables concise implementations with
reduced parasitics.
