74LV393 Dual 4-bit binary ripple counter Rev. 5 — 8 December 2015 Product data sheet 1. General description The 74LV393 is a low–voltage Si-gate CMOS device and is pin and function compatible with 74HC393 and 74HCT393. The 74LV393 is a dual 4-stage binary ripple counter. Each counter features a clock input (nCP), an overriding asynchronous master reset input (nMR) and 4 buffered parallel outputs (nQ0 to nQ3). The counter advances on the HIGH-to-LOW transition of nCP. A HIGH on nMR clears the counter stages and forces the outputs LOW, independent of the state of nCP. 2. Features and benefits          Optimized for low voltage applications: 1.0 V to 3.6 V Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V Typical VOLP (output ground bounce) 0.8 V at VCC = 3.3 V, Tamb = 25 C Typical VOHV (output VOH undershoot) 2 V at VCC = 3.3 V, Tamb = 25 C Two 4-bit binary counters with individual clocks Divide-by any binary module up to 28 in one package Two master resets to clear each 4-bit counter individually Complies with JEDEC standard no. 7A ESD protection:  HBM JESD22-A114F exceeds 2000 V  MM JESD22-A115-A exceeds 200 V 3.

Nexperia and its suppliers accept no liability for inclusion and/or use of Nexperia products in such equipment or applications and therefore such inclusion and/or use is at the customer’s own risk. Applications — Applications that are described herein for any of these products are for illustrative purposes only. Nexperia makes no representation or warranty that such applications will be suitable for the specified use without further testing or modification. Customers are responsible for the design and operation of their applications and products using Nexperia products, and Nexperia accepts no liability for any assistance with applications or customer product design. It is customer’s sole responsibility to determine whether the Nexperia product is suitable and fit for the customer’s applications and products planned, as well as for the planned application and use of customer’s third party customer(s). Customers should provide appropriate design and operating safeguards to minimize the risks associated with their applications and products. Nexperia does not accept any liability related to any default, damage, costs or problem which is based on any weakness or default in the customer’s applications or products, or the application or use by customer’s third party customer(s). Customer is responsible for doing all necessary testing for the customer’s applications and products using Nexperia products in order to avoid a default of the applications and the products or of the application or use by customer’s third party customer(s). Nexperia does not accept any liability in this respect. Limiting values — Stress above one or more limiting values (as defined in the Absolute Maximum Ratings System of IEC 60134) will cause permanent damage to the device. Limiting values are stress ratings only and (proper) operation of the device at these or any other conditions above those given in the Recommended operating conditions section (if present) or the Characteristics sections of this document is not warranted. Constant or repeated exposure to limiting values will permanently and irreversibly affect the quality and reliability of the device.

74LV393PW,118
物料型号:74LV393

器件简介: 74LV393是一款低压Si-gate CMOS设备,与74HC393和74HCT393引脚和功能兼容。它是一个双4位二进制滴答计数器,每个计数器具有时钟输入(nCP)、覆盖的异步主复位输入(nMR)和4个缓冲并行输出(nQ0至nQ3)。计数器在nCP的高到低转换时前进。nMR上的高电平会清除计数器阶段,并将输出强制为低,与nCP的状态无关。

引脚分配: - 1CP, 2CP: 时钟输入(高到低,边沿触发) - 1MR, 2MR: 异步主复位输入(高电平有效) - 1Q0-1Q3, 2Q0-2Q3: 触发器输出 - GND: 地(0V) - Vcc: 供电电压

参数特性: - 优化用于低电压应用:1.0 V至3.6 V - 接受在VCC = 2.7 V至VCC = 3.6 V之间的TTL输入电平 - 典型VOLP(输出地弹跳)在VCC = 3.3 V,环境温度25°C时为0.8 V - 典型VOHV(输出VOH下冲)在VCC = 3.3 V,环境温度25°C时为2 V - 符合JEDEC标准号7A的ESD保护

功能详解: 74LV393包含两个4位二进制计数器,每个计数器都有自己的时钟。每个计数器的计数序列从0到15,输出状态在每个时钟上升沿变化。

应用信息: 文档中没有提供具体的应用案例,但通常这类计数器可以用在需要计数或定时的数字电路中。

封装信息: 74LV393有三种封装类型: - 74LV393D: SO14封装,塑料小外形封装,14个引脚,体宽3.9毫米 - 74LV393DB: SSOP14封装,塑料收缩小外形封装,14个引脚,体宽5.3毫米 - 74LV393PW: TSSOP14封装,塑料薄型收缩小外形封装,14个引脚,体宽4.4毫米
