CD74HCT7046AM

Product Overview

The CD74HCT7046AM from Harris Corporation is a single-circuit phase-locked loop (PLL) integrated circuit intended for clock and timing functions. It uses CMOS input and CMOS output interfaces, operates from a 4.5 V to 5.5 V supply, and has a maximum frequency of 38 MHz. The device is packaged in a 16-SOIC surface-mount case with 0.154 in (3.90 mm) body width and supports an operating temperature range of -55°C to 125°C. The PLL has a 1:2 input-to-output ratio, non-differential input and output, and no divider or multiplier function.

Key Features

• Phase-locked loop (PLL) IC with one circuit and CMOS input/output.
• Maximum frequency of 38 MHz.
• Supply voltage range of 4.5 V to 5.5 V.
• Operating temperature range of -55°C to 125°C.
• 16-SOIC surface-mount package, 0.154 in (3.90 mm) width.
• 1:2 input-to-output ratio with non-differential input and output.
• No divider/multiplier function.

Applications

• Phase comparison in CMOS timing circuits.
• Frequency tracking for oscillator stabilization.
• Signal conditioning of periodic inputs up to 38 MHz.

Design & Procurement Notes

When using the CD74HCT7046AM, designers should verify that board-level supply rails remain within 4.5 V to 5.5 V and that input and output logic levels are CMOS compatible. The 38 MHz maximum frequency, 1:2 input-to-output ratio, and absence of divider/multiplier functions constrain achievable clocking relationships. For procurement, confirm that the 16-SOIC surface-mount footprint matches the board assembly process and that the -55°C to 125°C operating range is compatible with the intended environment. Because the device is a single PLL circuit with non-differential interfaces, system-level filtering, reference routing, and output loading should be planned around those characteristics.
