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.
