SN74LVC138APWT ti SN74LVC138A, 3-Line to 8-Line Decoder/demultiplexer Some Part number from the same manufacture Texas Instruments, Inc. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.įUNCTION TABLE ENABLE INPUTS G2A G2B SELECT INPUTS Y1 Y2 OUTPUTS Y6 Y7 Inputs can be driven from either or 5-V devices. An enable input can be used as a data input for demultiplexing applications. A 24-line decoder can be implemented without external inverters, and a 32-line decoder requires only one inverter. Two active-low enable inputs and one active-high enable input reduce the need for external gates or inverters when expanding. The conditions at the binary-select inputs and the three enable inputs select one of eight output lines. This means that the effective system delay introduced by the decoders is negligible. When employed with high-speed memories utilizing 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. In high-performance memory systems, these decoders minimize the effects of system decoding. The 'LVC138A devices are designed for high-performance memory-decoding or data-routing applications requiring very short propagation delay times. On all other products, production processing does not necessarily include testing of all parameters. On products compliant to MILPRF38535, all parameters are tested unless otherwise noted. Production processing does not necessarily include testing of all parameters. Products conform to specifications per the terms of Texas Instruments standard warranty.
