74ABT162244CMTD

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT162244CMTD is a 16-bit buffer and line driver featuring integrated 25Ω series resistors in the outputs. It utilizes ABT technology for high-speed performance with a supply voltage range of 4.5V to 5.5V. The device provides non-inverting buffers with 3-state outputs, controlled by four independent nibble enable inputs (OE1-OE4). Propagation delay ranges from 1.0ns to 4.7ns depending on load conditions. It operates within an ambient temperature range of -40°C to +85°C and is housed in a 48-lead Thin Shrink Small Outline Package (TSSOP).
