MC74VHC244DTR2G Description

Short technical summary and product information.

The MC74VHC244DTR2G from ON Semiconductor is an advanced, high-speed CMOS octal bus buffer designed for 3-state memory address drivers and similar applications. This non-inverting buffer features two active-low output enables and operates over a wide voltage range of 2.0V to 5.5V.

 

Fabricated with silicon gate CMOS technology, the device offers high noise immunity and balanced propagation delays. The MC74VHC244 is suitable for interfacing 5V systems to 3V systems due to its input voltage tolerance up to 5.5V. The output structures provide protection when VCC is 0V, preventing device destruction from voltage mismatches.

 

Key electrical characteristics include a typical propagation delay of 3.8 ns at 5.0V (VHC). It dissipates low power, with a maximum ICC of 4.0 mA at 25°C. The device exhibits high noise immunity with VNIH and VNIL at 28% and low noise output with VOLP at 0.8V (VHC) or 1.1V (VHCT).

 

Packaged in a 20-TSSOP, the MC74VHC244DTR2G is designed for surface mounting. It offers robust performance with latchup exceeding 100 mA and ESD protection greater than 2000V (Human Body Model). This component is Pb-free and halogen-free, complying with RoHS standards.
