SN74LS377N TI Flip Flop IC | 20-PDIP | D-Type, Non-Inverting, 8-Bit

Product Overview

The SN74LS377N is a high-performance octal D-type flip-flop with a buffered common clock and a buffered common output enable. Manufactured by Texas Instruments (TI), this device is part of the 74LS family, offering low-power Schottky technology. It features eight edge-triggered D-type flip-flops with individual data inputs (D0–D7) and outputs (Q0–Q7). The common clock (CP) loads data on the rising edge, while the common output enable (OE) controls the outputs. When OE is low, the outputs follow the internal flip-flop states; when high, the outputs are in a high-impedance state. The SN74LS377N is housed in a 20-pin PDIP package, making it suitable for through-hole PCB assembly. It operates over a wide voltage range of 4.75V to 5.25V and is characterized for operation from 0°C to 70°C.

產品概述

SN74LS377N 是一款高性能八路 D 型觸發器，具有緩衝公共時鐘和緩衝公共輸出使能。由德州儀器 (TI) 製造，屬於 74LS 系列，採用低功耗肖特基技術。它包含八個邊緣觸發的 D 型觸發器，帶有獨立數據輸入 (D0–D7) 和輸出 (Q0–Q7)。公共時鐘 (CP) 在上升沿加載數據，公共輸出使能 (OE) 控制輸出。當 OE 為低電平時，輸出跟隨內部觸發器狀態；當 OE 為高電平時，輸出處於高阻抗狀態。SN74LS377N 採用 20 引腳 PDIP 封裝，適合通孔 PCB 組裝。工作電壓範圍為 4.75V 至 5.25V，工作溫度範圍為 0°C 至 70°C。
