CD74HC147E Description

Short technical summary and product information.

The CD74HC147E from Texas Instruments is a high-speed silicon-gate CMOS 9-input priority encoder. This device is pin-compatible with low-power Schottky TTL (LSTTL) and operates over a wide temperature range of -55°C to 125°C.

 

It accepts data from nine active LOW inputs (I1 to I9) and provides a binary representation on four active LOW outputs (Y0 to Y3). A priority is assigned to each input, ensuring that when multiple inputs are active simultaneously, the input with the highest priority is represented on the output. Input line I9 has the highest priority.

 

The device offers a wide operating voltage range, supporting 2V to 6V for HC types. It features buffered inputs and outputs, with typical propagation delay of 13ns at 5V. Standard outputs can drive 10 LSTTL loads, while bus driver outputs can drive 15 LSTTL loads.

 

The CD74HC147E is available in various package types including 16-Lead PDIP, 16-Lead SOIC, 16-Lead SOP, 16-Lead TSSOP, and 16-Lead CERDIP. Mounting is typically through-hole.
