Latches datasheet and documents for DM74ALS573BN

DM74ALS573BN

Latches Overview

The DM74ALS573BN is an octal D-type transparent latch with 3-STATE outputs manufactured by onsemi. It operates within a supply voltage range of 4.5V to 5.5V and supports a free air operating temperature from 0°C to +70°C. The device features propagation delays ranging from 2ns to 14ns for data inputs and up to 20ns for enable signals, measured at 50 pF load. Output drive capabilities include -2.6mA high-level and 24mA low-level currents. It utilizes a 20-Lead Plastic Dual-In-Line Package (PDIP).

Latches Feature Summary

Transparent D-type latching behavior where outputs follow data inputs while the enable signal is HIGH.
High-impedance state capability allowing direct connection to bus lines without interface components.
Buffered output control input isolates internal latch operation from external output states.

Latches Applications

Implementing buffer registers in digital systems.
Serving as I/O ports for peripheral interfacing.
Functioning as bidirectional bus drivers.
Operating as working registers within microprocessor architectures.

Latches Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm package integrity and pin alignment against the N20A specification. Ensure environmental compliance documentation matches current regulatory standards. Validate that the specific ordering code corresponds to the PDIP variant rather than SOIC or SOP packages.

Latches Selection Notes

Select this component when designing systems requiring octal data storage with tri-state bus interfacing capabilities. Consider the Advanced Schottky TTL process for improved AC performance relative to standard LS logic families. Evaluate power consumption requirements against the specified supply current ranges under various output conditions.

Latches Part Context

This device belongs to the 74ALS series of logic integrated circuits. It is functionally equivalent to the DM74LS373 but offers improved switching characteristics at approximately half the power consumption. The technology utilizes an advanced oxide-isolated, ion-implanted Schottky process designed for driving highly capacitive loads.
