74HC259BQ规格书详情
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. Features and benefits
• Wide supply voltage range from 2.0 V to 6.0 V
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
• Complies with JEDEC standards:
• JESD8C (2.7 V to 3.6 V)
• JESD7A (2.0 V to 6.0 V)
• Combined demultiplexer and 8-bit latch
• Serial-to-parallel capability
• Output from each storage bit available
• Random (addressable) data entry
• Easily expandable
• Common reset input
• Useful as a 3-to-8 active HIGH decoder
• Input levels:
• For 74HC259: CMOS level
• For 74HCT259: TTL level
• ESD protection:
• HBM: ANSI/ESDA/Jedec JS-001 Class 2 exceeds 2000 V
• CDM: ANSI/ESDA/Jedec JS-002 Class C3 exceeds 1000 V
• Multiple package options
• Specified from -40 °C to +85 °C and from -40 °C to +125 °C
74HC259BQ属于集成电路(IC) > 锁存器。安世半导体(中国)有限公司制造生产的74HC259BQ锁存器锁存器是类似于触发器的基本数字存储设备,但是不同之处在于,在锁存使能(或类似命名)信号处于有效逻辑状态的任何时间,保持的逻辑状态都可以改变。“透明”锁存器还允许设备输出在锁存使能信号有效时反映输入的当前状态,而相反的是,状态仅在保持状态已固定时改变。
