74HCT2G17GW,125

Overview

The Nexperia 74HCT2G17GW,125 is a dual non-inverting Schmitt trigger buffer housed in a TSSOP6 (SOT363-2) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL-level input compatibility and includes internal clamp diodes on its inputs. Static characteristics specify a maximum low-level output voltage of 0.26 V at 4.0 mA load and a maximum high-level output voltage drop of 0.68 V under similar conditions. Dynamic performance indicates a typical propagation delay of 21 ns at 4.5 V with a 50 pF load.

Feature Summary

• Schmitt-trigger inputs convert slowly changing signals into sharply defined jitter-free outputs
• TTL-level input logic compatibility for direct interfacing with standard logic families
• Input clamp diodes enable safe interface to voltages exceeding the supply rail using current limiting resistors

Applications

• Wave and pulse shaping in highly noisy environments
• Astable multivibrator circuits
• Monostable multivibrator circuits

Procurement Notes

Verify that the specific application environment remains strictly within the recommended operating conditions of 4.5 V to 5.5 V supply voltage. Confirm that the thermal management design accommodates the specified power dissipation derating curves for the TSSOP6 package above 83 °C. Ensure input signals do not exceed absolute maximum ratings without appropriate external current limiting components.

Selection Notes

Select this component when TTL-level input thresholds are required for 5 V logic systems. The HCT variant is distinct from HC versions due to its specific input voltage levels. Verify that the dual-channel configuration fits the board space constraints of the SOT363-2 package compared to single-channel alternatives.

Part Context

This part belongs to the Nexperia 74HCT series of CMOS logic devices. It shares the same physical footprint as the 74HC2G17 but utilizes different internal threshold specifications to match TTL standards. The 'GW' suffix denotes the TSSOP6 plastic thin shrink small outline package with a body width of 1.25 mm.

Replacement Considerations

The 74HC2G17GW,125 is a pin-compatible alternative within the same family, though it requires CMOS-level input signals rather than TTL levels.
