74LVT574DB Description

Short technical summary and product information.

The 74LVT574DB is a high-performance, 8-bit, edge-triggered register with 3-state output buffers, designed for VCC operation at 3.3V. This device is suitable for bus interfacing applications, with inputs and outputs arranged for easy integration with microprocessors.

The flip-flop section is controlled by a clock (CP) input, and the 3-state output buffers are managed by a common active-low output enable (OE) control. When OE is low, the stored data is present at the outputs; when OE is high, the outputs enter a high-impedance state, preventing bus loading.

Key features include TTL input and output switching levels, with interface capability to 5V systems. Bus hold data inputs eliminate the need for external pull-up resistors. The device is specified for operation across a wide temperature range of -40°C to +85°C. It is supplied in an SSOP20 package suitable for surface mounting.

This component offers robust protection, including latch-up protection exceeding 500 mA (JESD78 Class II) and ESD protection exceeding 2000V (HBM) and 200V (MM). Live insertion and extraction are permitted, and there is no bus current loading when the output is tied to a 5V bus.
