MC14504B数据手册集成电路（IC）的转换器电平移位器规格书PDF

描述 Description

The MC14504B is a hex non-inverting level shifter using CMOS technology. The level shifter will shift a TTL signal to CMOS logic levels for any CMOS supply voltage between 5 and 15 volts. A control input also allows interface from CMOS to CMOS at one logic level to another logic level: Either up or down level translating is accomplished by selection of power supply levels VDD and VCC. The VCC level sets the input signal levels while VDD selects the output voltage levels.

特性 Features

• UP Translates from a Low to a High Voltage or DOWN Translates from a High to a Low Voltage
• Input Threshold Can Be Shifted for TTL Compatibility
• No Sequencing Required on Power Supplies or Inputs for Power Up or Power Down
• 3 to 18 Vdc Operation for VDD and VCC
• Diode Protected Inputs to VSS
• Capable of Driving Two Low-Power TTL Loads or One Low-Power Schottky TTL Load Over the Rated Temperature Range
• Pb-Free Packages are Available*

简介

MC14504B属于集成电路（IC）的转换器电平移位器。由制造生产的MC14504B转换器，电平移位器逻辑转换器或电平移位器 IC 可用于在数字逻辑设备之间传递信息，这些设备可在不同/不兼容的供电电压下工作，或可实现不同的信令方式。例如，可以将需要 5 V 电源的数字输出传感器连接到具有 3.3 V I/O 电源的 FPGA，或者在 CMOS 或 TTL 等单端信令方式与 PECL 或 LVDS 等差分技术之间进行转换。
