DESCRIPTION

· The 74LVC139 is a dual 2-to-4 line decoder/demultiplexer.

· It decodes two binary weighted address inputs to four mutually exclusive outputs.

· Each decoder features an enable input, which forces all outputs HIGH when activated.

· The enable input can also function as a data input for 1-to-4 demultiplexer applications.

· Inputs are compatible with both 3.3 V and 5 V devices, making it suitable for mixed voltage environments.

· Schmitt-trigger action ensures tolerance to slower input rise and fall times.

FEATURES

· Wide supply voltage range: 1.2 V to 3.6 V.

· Overvoltage tolerant inputs up to 5.5 V.

· Low power CMOS technology.

· Direct interface with TTL levels.

· Two independent 2-to-4 decoders with demultiplexing capability.

· Output drive capability: 50 Ω transmission lines at 125 °C.

· Complies with JEDEC standards for various voltage ranges.

· ESD protection: HBM exceeds 2000 V, CDM exceeds 1000 V.

· Available in multiple package options.

· Operating temperature range: -40 °C to +125 °C.

APPLICATIONS

· Used in mixed 3.3 V and 5 V environments as voltage translators.

· Suitable for demultiplexing and decoding applications.

· Ideal for interfacing with TTL logic levels.

· Can be used in systems requiring robust ESD protection.

· Suitable for high-temperature environments up to 125 °C.
