The TC74AC138FTEL is a logic-signal switch, multiplexer and decoder. It is a true high-speed CMOS device that allows multiplexing and decoding functions to be accurately and reliably achieved with minimal power consumption. It is one of the key components of an integrated circuit (IC).

This device is basically a three-to-eight line decoder with one active-low enable input (E). It has an AND-OR-INVERT (AOI) logic circuit which is used to multiplex and decode inputs. The three-bit (A0, A1 and A2) inputs select one of eight output lines which have a logic ‘1’ level when enabled. The active-low enable line (E) is used to control the output, when it is at a logic ‘1’ level all output lines are at a logic ‘ 1 ’, otherwise all outputs are at a logic ‘ 0’. The device can also be used as a three-line-to-eight-line multiplexer.

The TC74AC138FTEL operates over a wide range of input (VCC) and output (VDD) voltages. It can be used in systems operating from 5V to 18V, both unidirectional and bidirectional. The output currents are normally in excess of 5 mA and can be as high as 23 mA, depending on the operating temperature range. With the device in this operating condition, the power dissipation is usually less than 2W.

The device also has built-in protection against static discharge damage. It provides ESD protection of greater than 4KV HBM on all pins. This ensures that the device is protected from transient voltage spikes. It also has a low-noise package, which helps to reduce the power required to drive logic signals.

The TC74AC138FTEL is used for applications such as multi-level address encoding and decoding, programmable logic device (PLD) address decoding, instruction decoding and ROM address decoding. It is also used in memory and gate array decoders, frequency synthesizers, digital signal processors (DSP), and many other logic applications.

The device is available in packages such as the PDIP, SOIC, and TSSOP. The lead profile is optimized to guarantee reliability even at high switching frequency. The device can operate at a frequency above 1.0GHz with minimal propagation delay. The propagation delay is typically less than 0.5 ns.

The TC74AC138FTEL is a powerful logic-signal switch, multiplexer, and decoder. It is a high-performance, low-power device that can be used in many applications. It is a true high-speed CMOS device that allows for multiplexing and decoding functions to be accurately and reliably achieved with minimal power consumption.
