Overview
The 74HC573BQ-Q100,115 is an 8-bit D-type transparent latch with 3-state outputs, manufactured by Nexperia USA Inc. This component is part of the 74HC573-Q100 series, which is automotive-qualified according to the Automotive Electronics Council (AEC) standard Q100 (Grade 1). It operates within a temperature range of -40°C to +125°C, making it suitable for various automotive and industrial applications.
The device features latch enable (LE) and output enable (OE) inputs. When the LE input is HIGH, the latches are transparent, allowing the output to change with the input. When LE is LOW, the latches store the information present at the inputs. A HIGH on the OE input causes the outputs to assume a high-impedance OFF-state without affecting the latch state.
