HD74LV139A

Dual 2-to-4 line Decoder / Demultiplexers

ADE-205-262 (Z)

1st Edition

March 1999

Description

The HD74LV139A is designed to be used in high-performance memory-decoding or data-routing
applications requiring very short propagation delay times. The active-low enable input can be used as a
data line in demultiplexing applications.
This decoder/demultiplexer features fully buffered inputs, each of which represents only one normalized
load to its driving circuit.
Low-voltage and high-speed operation is suitable for the battery-powered products (e.g., notebook
computers), and the low-power consumption extends the battery life.

Features

• VCC = 2.0 V to 5.5 V operation

• All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V)

• All outputs VO (Max.) = 5.5 V (@VCC = 0 V)

• Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)

• Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°C)

• Output current ±6 mA (@VCC = 3.0 V to 3.6 V), ±12 mA (@VCC = 4.5 V to 5.5 V)

Notes: The absolute maximum ratings are values which must not individually be exceeded, and furthermore,

no two of which may be realized at the same time.

1. The input and output voltage ratings may be exceeded if the input and output clamp-current
ratings are observed.

2. This value is limited to 5.5 V maximum.

3. The maximum package power dissipation was calculated using a junction temperature of 150°C.
