These octal flip-flops are designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.
The SN54LVTH374 is a low‑voltage (3.3 V) octal edge‑triggered D‑type flip‑flop with three‑state outputs, designed for mixed‑mode signal operation and hot‑insertion applications. It offers bus‑hold circuitry, buffered output‑enable control, and support for unregulated battery operation down to 2.7 V.
Key features include a wide range of package options (SOIC‑DW, SSOP‑DB, TSSOP‑PW, CDIP‑J, CFP‑W, etc.), ESD protection exceeding JESD‑22, and specifications such as supply voltage 2.7‑3.6 V, operating temperature –55 °C to 125 °C, and low‑level output current up to 64 mA.
