HD74BC245A
Octal Transceivers With State Outputs
ADE-205-008B 3rd. Edition Sep. 2000 Description
HD74BC245A provides high drivability operation equal better than high speed bipolar standard logic using Bi-CMOS process. device features power dissipation that about high speed bipolar logic when frequency MHz. device buffers with three state outputs package. Each device active enable input direction control input DiR. When high, data flows from inputs outputs. When low, data flows from inputs outputs. When high, disables both ports placing then high impedance.
Features
Input/Output high impedance state when power supply off. Built input pull circuit make input pins open, when used. level input Wide operating temperature range 85°C
