The TL331B-Q1 and TL391B-Q1 devices are the next generation versions of the industry-standard TL331-Q1 comparator. These next generation devices provide outstanding value for cost-sensitive applications, with features including lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, dedicated ESD protection cells with improved negative input voltage handling. The TL331B-Q1 can drop-in replace both the TL331-Q1 "I" and "Q" versions. The TL391B-Q1 provides an alternate pinout of the TL331B-Q1. The TL331E-Q1 extends the temp range up to 150ºC, meeting AEC-Q100 Grade 0 temperature requirements. This device consists of a single voltage comparator designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible if the difference between the two supplies is 2V to 36V and VCC is at least 1.5V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. To achieve wired-AND relationships, one can connect the output to other open-collector outputs.

The LV device family consists of single, dual and quad independent voltage comparators that operate from a wide supply voltage range. The LV devices can drop-in replace the standard TL331, LM2xx, LM3xx and LM290x comparator family in low voltage (≤ 5 V) applications for improved performance and added features. The LV devices include a Power-On-Reset (POR) feature to make sure the output is in a High-Z state until the minimum supply voltage has been reached to prevent output transients during power-up and power-down. The family also feature Rail to Rail inputs that can go up to 6 V without damage or phase inversion. The LV devices are specified for the temperature range of -40°C to +125°C, which covers the ranges of the TL331, LM2xx, LM3xx and LM290x comparator families.

The TL3414A device is a dual operational amplifier that can be operated with single or dual power supplies. In addition to high gain and high output voltage swing, it is capable of driving a 70-mA load, making it ideally suited for simple, low-cost audio-amplifier applications, such as headphone amplifiers in DVD and CDRW applications.

The TL343 is a single operational amplifier similar in performance to the µA741, but with several distinct advantages. It is designed to operate from a single supply over a range of voltages from 3 V to 30 V. Operation from split supplies also is possible, provided the difference between the two supplies is 3 V to 30 V. The common-mode input range includes the negative supply. Output range is from the negative supply to VCC– 1.5 V. The TL343 is a single operational amplifier similar in performance to the µA741, but with several distinct advantages.

Quality, low-cost, bipolar fabrication with innovative design concepts are employed for the TL3472 operational amplifier. This device offers 4 MHz of gain-bandwidth product, 13-V/µs slew rate, and fast settling time, without the use of JFET device technology. Although the TL3472 can be operated from split supplies, it is particularly suited for single-supply operation because the common-mode input voltage range includes ground potential (VCC-). With a Darlington transistor input stage, this device exhibits high input resistance, low input offset voltage, and high gain. The all-npn output stage, characterized by no dead-band crossover distortion and large output voltage swing, provides high-capacitance drive capability, excellent phase and gain margins, low open-loop high-frequency output impedance, and symmetrical source/sink ac frequency response. This low-cost amplifier is an alternative to the MC33072 and the MC34072 operational amplifiers.
