74LCX16245MEA

Overview

The onsemi 74LCX16245MEA is a dual 8-bit bus transceiver with non-inverting logic, housed in a 48-SSOP package. It operates within a supply voltage range of 2V to 3.6V and supports LVTTL/TTL input levels with LVCMOS output levels. The device features three-state outputs capable of sourcing and sinking 24mA. It has a maximum propagation delay of 5.2ns at 50pF load and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual 8-bit bidirectional bus transceiver architecture
• Non-inverting logic functionality
• Three-state output capability for bus isolation
• Bus hold feature to prevent floating inputs

Applications

• Memory bus architectures
• High-density data acquisition systems
• Computing and instrumentation equipment

Procurement Notes

This component is obsolete and no longer manufactured by onsemi. Sourcing new units from original channels is not possible. Engineers must verify the authenticity and condition of any available surplus stock carefully. Replacement strategies should prioritize direct substitutes or pin-compatible alternatives that meet the same electrical specifications to ensure system continuity.

Selection Notes

Designers requiring this specific part number must evaluate alternative components due to its end-of-life status. Selection criteria should focus on matching the 48-pin SSOP footprint, 2V-3.6V operating voltage, and 24mA drive current. Verify that replacement devices offer identical propagation delays and thermal characteristics to maintain signal integrity in existing high-speed digital designs without requiring layout modifications.

Part Context

The 74LCX16245MEA belongs to the 74LCX family of low-voltage CMOS logic devices. This series is designed for applications requiring low power consumption and high speed. The device integrates two independent 8-bit transceivers, providing efficient data transfer between buses. Its compatibility with standard logic families makes it suitable for various digital interface applications in consumer and industrial electronics.

Replacement Considerations

Direct substitute: SN74LVC16245ADL (Texas Instruments). Similar alternative: 74LVCH16245APAG (Renesas Electronics Corporation).
