HD74LV4051A

8-channel Analog Multiplexer / Demultiplexer

ADE-205-283 (Z)

1st Edition
April 1999

Description

The HD74LV4051A handles both analog and digital signals, and enables signals of either type with
amplitudes of up to 5.5 V (peak) to be transmitted in either direction (at VCC = 0 V to 5.5 V).
Applications include signal gating, chopping, modulation or demodulation (modem), and signal
multiplexing for analog-to-digital and digital-to-analog conversion systems.

Features

• VCC = 2.0 V to 5.5 V operation

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

Notes: Unused or floating inputs must be held high or low.

1. With the supply voltage at or around 2 V, the analog switch on-state loses linearity significantly.
It is recommended that only digital signals be transmitted at these low supply voltages.
