description (continued)
The TLC2654 and TLC2654A common-mode
input voltage range includes the negative rail,
thereby providing superior performance in either
single-supply or split-supply applications, even at
power supply voltage levels as low as
±2.3 V.
Two external capacitors are required to operate
the device; however, the on-chip chopper-control
circuitry is transparent to the user. On devices in
the 14-pin and 20-pin packages, the control
circuitry is accessible, allowing the user the option
of controlling the clock frequency with an external
frequency source. In addition, the clock threshold
of the TLC2554 and TLC2654A requires no level
shifting when used in the single-supply configura-
tion with a normal CMOS or TTL clock input.
Innovative
circuit
techniques
used
on
the
TLC2654 and TLC2654A allow exceptionally fast
overload recovery time. An output clamp pin is
available to reduce the recovery time even further.
The device inputs and outputs are designed to
withstand
– 100-mA
surge
currents
without
sustaining latch-up. In addition, the TLC2654 and TLC2654A incorporate internal ESD-protection circuits that
prevent functional failures at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015; however,
exercise care in handling these devices, as exposure to ESD may result in degradation of the device parametric
performance.
The C-suffix devices are characterized for operation from 0
°C to 70°C. The I-suffix devices are characterized
for operation from – 40
°C to 85°C. The Q-suffix devices are characterized for operation from –40°C to 125°C.
The M-suffix devices are characterized for operation over the full military temperature range of – 55
°C to125°C.
