74LVC2245ADB集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

DESCRIPTION

The 74LVC2245A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families.

Inputs can be driven from either 3.3 or 5 V devices. In 3-state operation, outputs can handle 5 V. These features allow the use of these devices as translators in a mixed 3.3 and 5 V environment.

The 74LVC2245A is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions.

The 74LVC2245A features an output enable (OE) input for easy cascading and a send/receive (DIR) input for direction control. OE controls the outputs so that the buses are effectively isolated.

The 74LVC2245A is designed with 30 Ω series termination resistors in both HIGH and LOW output stages to reduce line noise.
