A20300S - SN74ACT1284DBR SMD 7-Bit Bus Interfaces (TI)

A20300S - SN74ACT1284DBR SMD 7-Bit Bus Interfaces (TI)

item number: A20300S
unit price:£1.00 

Detailed Description

The SN74ACT1284DBR is designed for asynchronous two-way communication between data buses. The control function minimizes external timing requirements. The devices allow data transmission in either the A-to-B or the B-to-A direction for bits 1, 2, 3, and 4, depending on the logic level at the direction-control (DIR) input. Bits 5, 6, and 7, however, always transmit in the A-to-B direction. The output drive for each mode is determined by the high-drive (HD) control pin. When HD is high, the high drive is delivered by the totem-pole configuration, and when HD is low, the outputs are open drain.

4.5-V to 5.5-V VCC Operation
Inputs Accept Voltages to 5.5 V
Max tpd of 20 ns at 5 V
3-State Outputs Directly Drive Bus Lines
Flow-Through Architecture Optimizes PCB Layout
Center-Pin VCC and GND Configurations Minimize High-Speed Switching Noise
