SN74ALS648ANT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS648ANT is an octal bus transceiver and register manufactured by Texas Instruments, belonging to the Advanced Low-power Schottky (ALS) logic series. It features eight channels with three-state outputs and inverting polarity, housed in a 24-pin Plastic Dual In-line Package (PDIP). The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a temperature range of 0°C to +70°C. Key electrical characteristics include a propagation delay of 30 ns, a low-level output current of 24 mA, and a high-level output current of -15 mA.
