Description

The MC1488, SN55188, and SN75188 are monolithic quadruple line drivers designed to interface data terminal equipment with data communications equipment in conformance with ANSI EIA/TIA-232-E using a diode in series with each supply-voltage terminal as shown under typical applications.

The SN55188 is characterized for operation over the full military temperature range of –55°C to 125°C.

Part Number: SN74LVC138

Function: 3-LINE TO 8-LINE DECODERS/DEMULTIPLEXERS

Manufacturer: Texas Instruments

Description

The SN74LVC138 devices are designed for highperformance memory-decoding or data-routing
applications requiring very short propagation delay times. In high-performance memory systems, these decoders minimize the effects of system decoding.

When employed with high-speed memories using a fast enable circuit, delay times of these decoders and the enable time of the memory usually are less than the typical access time of the memory. This means that the effective system delay introduced by the decoders is negligible.

Features

1. Operate From 1.65 V to 3.6 V

2. Inputs Accept Voltages to 5.5 V

3. Max tpd of 5.8 ns at 3.3 V

Applications:

• LED Displays

• Servers

• White Goods

• Power Infrastructure

• Building Automation

• Factory Automation
