SN74AHC16540DL TI Buffer/Driver | 48-SSOP | 8-bit, 3-State, 2V-5.5V

Product Overview

The SN74AHC16540DL is an advanced high-speed CMOS octal buffer/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 buffering memory address registers. The device is organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When OE is low, the outputs are in the high-impedance state. The inputs are tolerant to 5.5 V, allowing down-translation to VCC. This device is fully specified for partial-power-down applications using Ioff, which disables the outputs when VCC is 0 V, preventing damaging backflow current.

產品概述

SN74AHC16540DL 是德州儀器推出的先進高速 CMOS 八路緩衝器/驅動器，工作電壓範圍為 2 V 至 5.5 V。具有三態輸出，適用於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，每個帶有單獨的輸出使能 (OE) 輸入。當 OE 為低電平時，輸出處於高阻抗狀態。輸入可承受高達 5.5 V 的電壓，支援向下轉換至 VCC。該器件完全支援部分斷電應用，利用 Ioff 電路在 VCC 為 0 V 時禁用輸出，防止反向電流損壞。
