HD74HC245FPEL中文资料瑞萨数据手册PDF规格书

Description

This device has an active low enable input G and a direction control input (DIR). When DIR is high, data flows from the A inputs to the B outputs. When DIR is low, data flows from the B inputs to the A outputs. The HD74HCT245 transfers true data from one bus to the other.

This device does not have schmitt trigger inputs.
