SN54HCT574 Overview
Description
These octal edge-triggered D-type flip-flops feature 3-state outputs designed specifically for bus driving. The ’HCT574 devices are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
Key Features
- Operating voltage range of 4.5 V to 5.5 V
- High-current 3-state noninverting outputs drive bus lines directly or up to 15 LSTTL loads
- Low power consumption, 80-μA max ICC
- Typical tpd = 22 ns
- ±6-mA output drive at 5 V
