The Data inputs are TTL/CMOS compatible and can also be driven up to the supply voltage VDD. The ENA input can be used to place all the outputs in a high impedance state. The OPD input is used to configure the outputs as push-pull drivers or open-drain drivers, where the outputs can be returned through external loads to a maximum voltage of VDD. LS7272B-20 does not have OPD pin and its outputs are always in push-pull configuration
An internal 5V regulated supply is used to power the logic and level converter blocks. The thermal shutdown block located in the center of the IC can be disabled by setting the ENA input, Pin 12, to a voltage between 7.5V and 12V.
Upon power-up, a Power-On-Reset (POR) circuit block forces all output drivers to the high-impedance state until the power supply voltage reaches a nominal 3.9V. Included in the POR circuit block is a hysteresis of 200mV such that if the power supply drops below 3.7V all output drivers are forced to the high-impedance state until the voltage rises above 3.9V. There is a built-in 5µs delay for disabling the output drivers should the power supply drop below 3.7V. The output drivers are immediately enabled when the voltage rises above 3.9V.
Features:
- More feature-rich and cost-effective than the OL7272
- Pin for pin replaceable with the OL7272
- Push-Pull or Open-Drain output drivers

Macnica’s ATD Europe GmbH, (former Macnica GmbH), was originally established in the UK in 2006, and moved to Germany in July 2008, to increase efficacy of its service for European customers.
By it’s acquisition of the Munich based company Scantec Mikroelektronik in 2014 Macnica Europe formed a powerful semiconductor distribution with headquarter in Ingolstadt and offices in Munich, Regensburg, Milton Keynes (UK) and Warsaw offering an attractive and competitive portfolio of highly sophisticated devices.
Macnica provides end to end support from designin to production through its global service network to its customers, regardless of the final destination of the product shipment to customers’ manufacturing locations.
About Macnica ATD Europe S.A.S.
Founded in 1990 as ATD Electronique, Macnica ATD Europe headquarter offers innovative components dedicated to imaging applications for the European market. Its product portfolio includes: image sensors (CCD, CMOS, InGaAs, Thermal etc.), optics, interface circuits, FPGA & IPs, imaging processors, cables and OLED microdisplays.
It also covers development tools and design services enabling fast and efficient realization of new highperformance camera systems for markets such as machine vision, medical, life sciences, surveillance, automotive and others. After the acquisition of the company by Macnica Inc. as of October 1, 2020 the company operates under the name Macnica ATD Europe.
