74LVT16244MEAX

Overview

The onsemi 74LVT16244MEAX is a low-voltage 16-bit buffer and line driver featuring 3-STATE outputs. It operates within a supply voltage range of 2.7V to 3.6V, with inputs tolerant up to 5.5V for TTL interface compatibility. The device provides high drive capability, sourcing up to -32mA and sinking up to 64mA per output. Propagation delays are specified between 1.2ns and 3.9ns depending on voltage conditions. It utilizes an advanced BiCMOS technology to achieve high-speed operation while maintaining low power dissipation.

Feature Summary

• Provides 16 non-inverting buffers with independent 3-STATE control for memory, address, or clock driving applications.
• Features input and output interface capabilities compatible with 5V systems despite low-voltage operation.
• Supports live insertion and extraction without causing bus current loading during power-up or power-down states.

Applications

• Memory and address drivers
• Clock drivers
• Bus-oriented transmitter/receiver circuits

Procurement Notes

Verify the specific ordering suffix 'MEA' corresponds to the 48-Lead Small Shrink Outline Package (SSOP) as documented in the datasheet. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards. Ensure the design accounts for the absolute maximum ratings regarding supply voltage and input/output currents to prevent device damage.

Selection Notes

Select this component when a 16-bit wide data path requires buffering with high drive strength and 3-STATE isolation. It is suitable for designs needing TTL-level interfacing from a 3.3V logic domain. Consider the SSOP package constraints for PCB layout. Verify that the required propagation delay falls within the specified 1.2ns to 3.9ns range for your system timing.

Part Context

This part belongs to the 74LVT series of low-voltage CMOS logic devices. It is functionally compatible with the standard 74 series 16244 but optimized for lower voltage operation. The device is manufactured using BiCMOS technology, which balances speed and power consumption effectively for general-purpose digital logic applications.

Replacement Considerations

The 74LVTH16244MEAX is a functional variant within the same family, distinguished by the inclusion of bus-hold data inputs. Designers requiring bus-hold functionality should consider this alternative instead of the base 74LVT16244 model.

FAQ

Does the 74LVT16244MEAX include bus-hold inputs?

No, the 74LVT16244 does not include bus-hold inputs. This feature is available only in the 74LVTH16244 variant.

What is the maximum input voltage tolerance?

The device supports input voltages up to 5.5V, allowing it to interface directly with 5V TTL logic systems.
