74ALVT162245DL中文资料16-bit transceiver with 30 Ohm termination resistors; 3-state数据手册Nexperia规格书

描述 Description

The 74ALVT162245 is a high-performance BiCMOS product designed for VCC operation at 2.5 V or 3.3 V with I/O compatibility up to 5 V.
This device is a 16-bit transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. The device features an output enable input (nOE) for easy cascading and a direction control input (nDIR) for direction control.
The 74ALVT162245 is designed with 30 Ω series resistance in both the HIGH-state and LOW-state of the output. This design reduces line noise in applications such as memory address drivers, clock drivers and bus transceivers and transmitters.
