SNJ54LVTH574FK TI Flip-Flop | 3.3V, 8-bit, D-Type, Bus-Hold

Product Overview

The SNJ54LVTH574FK is a high-performance, 8-bit D-type flip-flop from Texas Instruments, designed for 3.3V operation with 5V-tolerant inputs. It features bus-hold circuitry to eliminate the need for external pull-up/pull-down resistors, reducing component count and board space. This device is part of the LVTH family, offering low-voltage operation with high drive capability (±32 mA output sink/source). The SNJ54LVTH574FK is packaged in a 20-pin ceramic flatpack (CFP) and is specified for military temperature range (-55°C to +125°C), making it suitable for harsh environments.
