SN74LV138APWR Description

Short technical summary and product information.

The SN74LV138A is a 3-line to 8-line decoder/demultiplexer from Texas Instruments, designed for operation with a VCC range of 2V to 5.5V. The device features conditions at the binary-select inputs (A0, A1, A2) and three enable inputs (G2, G0, G1) that select one of eight output lines. The two active-low enable inputs (G0, G1) and one active-high enable input (G2) simplify system design by reducing the need for external gates or inverters when expanding functionality.

 

This component has a maximum propagation delay of 9.5 ns at 5V. It supports mixed-mode voltage operation on all ports and includes an Ioff feature for partial-power-down mode operation. Latch-up performance exceeds 250 mA per JESD 17. The SN74LV138APWR is supplied in a 16-TSSOP package suitable for surface mounting.

 

Key electrical characteristics include a typical output ground bounce of less than 0.8V and a typical output VOH undershoot greater than 2.3V, both measured at VCC = 3.3V and TA = 25°C. The operating temperature range is -40°C to 85°C.
