74HC259; 74HCT259 8-bit addressable latch Rev. 7 — 2 September 2020 Product data sheet 1. General description The 74HC259; 74HCT259 is an 8-bit addressable latch. The device features four modes of operation. In the addressable latch mode, data on the D input is written into the latch addressed by the inputs A0 to A3. The addressed latch will follow the data input, non-addressed latches will retain their previous states. In memory mode, all latches retain their previous states and are unaffected by the data or address inputs. In the 3-to-8 decoding or demultiplexing mode, the addressed output follows the D input and all other outputs are LOW. In the reset mode, all outputs are forced LOW and unaffected by the data or address inputs. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. 2.

物料型号: - 型号:74HC259; 74HCT259 - 描述:8位可寻址锁存器

器件简介: - 74HC259和74HCT259是8位可寻址锁存器,具有四种工作模式。在可寻址锁存器模式下,D输入端的数据将被写入由A0至A3输入寻址的锁存器。在存储模式下,所有锁存器保留先前状态,不受数据或地址输入影响。在3至8解码或解复用模式下,被寻址的输出跟随D输入,所有其他输出为低电平。在复位模式下,所有输出被强制为低电平,不受数据或地址输入影响。

引脚分配: - 引脚包括地址输入(A0, A1, A2)、数据输入(D)、锁存器输出(Q0至Q7)、锁存器使能输入(LE)、条件复位输入(MR)、电源电压(Vcc)和地(GND)。

参数特性: - 工作电压范围宽,从2.0V至6.0V。 - 锁存性能超过100mA,符合JESD 78 Class II Level B标准。 - 符合JEDEC标准JESD8C (2.7V至3.6V)和JESD7A (2.0V至6.0V)。 - 具有串行到并行的能力,每个存储位的输出都可用。 - 输入电平:74HC259为CMOS电平,74HCT259为TTL电平。 - ESD保护:HBM JESD22-A114F超过2000V,MM JESD22-A115-A超过200V,CDM JESD22E超过1000V。 - 多种封装选项,规定了从-40°C至+85°C和从-40°C至+125°C的温度范围。

功能详解: - 提供了功能表和操作模式选择表,详细描述了在不同输入条件下的输出状态。

应用信息: - 可用作3至8主动高电平解码器,具有通用复位输入,易于扩展。

封装信息: - 提供了三种不同的封装类型:SO16、TSSOP16和DHVQFN16,每种封装都有详细的引脚配置和描述。
