SN74AHC240DGVR TI Buffer/Driver | 20-TVSOP | 8-ch, 2V-5.5V

Product Overview

The SN74AHC240DGVR is a high-performance octal buffer and line driver from Texas Instruments, designed for 2-V to 5.5-V VCC operation. It features 3-state outputs and is ideal for driving bus lines or buffer memory address registers. The device is organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from A inputs to Y outputs; when OE is high, the outputs are in the high-impedance state. This part is offered in a 20-pin TVSOP package, which is space-saving and suitable for compact designs.

產品概述

SN74AHC240DGVR 是德州儀器（TI）的高性能八路緩衝器和線路驅動器，設計用於 2 V 至 5.5 V 的 VCC 操作。它具有三態輸出，非常適合驅動匯流排或緩衝記憶體位址暫存器。該器件由兩個獨立的 4 位元緩衝器/驅動器組成，每個都有單獨的輸出使能（OE）輸入。當 OE 為低電平時，數據從 A 輸入傳輸到 Y 輸出；當 OE 為高電平時，輸出處於高阻抗狀態。此型號採用 20 引腳 TVSOP 封裝，節省空間，適合緊湊型設計。
