Key Features
- Dual independent 2-to-4 line decoder/demultiplexer enabling simultaneous address decoding of 2 separate 2-bit buses in a single 16-pin TSSOP-16 package
- Wide 1.65 V to 5.5 V supply range for mixed-voltage system compatibility across 1.8 V, 3.3 V, and 5 V logic levels
- 24 mA IOL output sink current supporting direct LED drive and bus-load applications without external buffer
- LVC (Low Voltage CMOS) family with propagation delay below 10 ns at 3.3 V enabling high-speed address decode in 50 MHz+ bus systems
Applications
The 74LVC139PW,118 is widely used in microcontroller and FPGA peripheral address decoding, where a 2-bit address bus must select one of 4 active-low chip-select outputs to enable SRAM, Flash, or peripheral ICs. Its dual-decoder architecture in a compact TSSOP-16 package makes it ideal for memory-mapped I/O expansion on embedded Linux boards, industrial PLC I/O cards, and communication modules operating at 3.3 V or 5 V logic levels.

Frequently Asked Questions
Which voltage supply range does the 74LVC139PW,118 support, and does it interface directly with both 3.3 V and 5 V logic?
The 74LVC139PW,118 operates from 1.65 V to 5.5 V supply voltage, making it directly compatible with 1.8 V, 3.3 V, and 5 V logic families without level-shifting. Its input thresholds track the supply rail, so a 3.3 V microcontroller can drive the address inputs while the decoder outputs interface with 5 V peripheral chip-select pins.
How does having two independent decoders in a single package benefit memory-mapped peripheral designs?
The dual 2-to-4 architecture provides 8 independent active-low chip-select outputs from just 4 address input lines and 2 enable pins within a 16-pin TSSOP-16 footprint. This eliminates a second decoder IC, reducing BOM cost by one part and saving approximately 30 mm2 of PCB area in compact embedded controller designs with 8 addressable peripherals.
Can the 74LVC139PW,118 drive LEDs or bus loads directly given its output current specification?
Yes. With a 24 mA maximum IOL sink current per output, each active-low output can directly drive a standard 5 mm or 3 mm LED with a series resistor, or sink the bus load of up to 8 standard CMOS inputs at 50 pF each without an external buffer, simplifying designs that combine address decoding with indicator light control.
What is the propagation delay at 3.3 V, and is the 74LVC139PW,118 fast enough for 50 MHz bus decode cycles?
At a 3.3 V supply and 50 pF load capacitance, the LVC family 74LVC139 typically achieves propagation delays below 10 ns from address input to decoded output, corresponding to a maximum decode throughput exceeding 100 MHz. This comfortably meets setup time requirements for 50 MHz peripheral buses and most 80 MHz microcontroller external bus interfaces.
