MC100EL91集成电路（IC）的转换器电平移位器规格书PDF中文资料

MC100EL91属于集成电路（IC）的转换器电平移位器。由安森美半导体公司制造生产的MC100EL91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。

Description

The MC100LVEL91 is a triple LVPECL input to ECL output translator. The device receives low voltage differential PECL signals, determined by the VCC supply level, and translates them to differential −3.3 V to −5.0 V ECL output signals.

To accomplish the level translation the LVEL91 requires three power rails. The VCC supply should be connected to the positive supply, and the VEE pin should be connected to the negative power supply. The GND pins are connected to the system ground plane. Both VEE and VCC should be bypassed to ground via 0.01 F capacitors.
