74ACT16841DL

The Texas Instruments 74ACT16841DL is a 20-bit bus-interface D-type latch designed for high-speed applications. It belongs to the ACT technology family and features TTL-compatible CMOS inputs and 3-state outputs, capable of driving bus lines directly.

Key electrical specifications include a maximum clock frequency of 90 MHz, an IOL of 24 mA, and an IOH of -24 mA. The device operates within a voltage range of 4.5V to 5.5V and has a low supply current of 80 µA. It offers a delay time of 7.7 ns and is organized into 2 independent circuits, each with a 10:10 configuration.

This latch is suitable for wider address/data paths or buses with parity, providing necessary bus driving and latching capabilities. The flow-through architecture optimizes PCB layout, and distributed VCC and GND pin configurations minimize high-speed switching noise. It is manufactured using an EPIC (Enhanced-Performance Implanted CMOS) 1-µm process with 500-mA typical latch-up immunity at 125°C.

The 74ACT16841DL is available in a 56-SSOP package and operates within an industrial temperature range of -40°C to 85°C. Its balanced outputs and positive input clamp diode are additional features contributing to its performance.
