74HC368PWJ

Overview

The Nexperia 74HC368PWJ is a hex inverting buffer and line driver featuring three-state outputs controlled by active-low output enable inputs (nOE). It operates within a supply voltage range of 2.0 V to 6.0 V, supporting CMOS input levels. The device includes input clamp diodes for interfacing with voltages exceeding VCC. It complies with JEDEC standards JESD8C and JESD7A, offering high noise immunity and latch-up performance exceeding 100 mA per JESD 78 Class II Level B. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). It is specified for ambient temperatures from -40 °C to +125 °C.

• Memory data bus drivers

Procurement Notes

Verify the specific ordering suffix 'J' against official Nexperia documentation to confirm package variant or tape-and-reel specifications. Ensure the selected part number matches the required temperature range and package type (TSSOP16) for your design constraints. Cross-reference the latest datasheet revision to confirm current production status and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select the 74HC368 when an inverting function is required for bus driving applications. Choose this component over non-inverting variants like the 74HC244 if signal inversion is necessary. Consider the 74HCT368 if TTL logic levels are required at the inputs while maintaining compatibility with 5 V CMOS systems. Verify that the three-state control signals align with the system's bus arbitration requirements.

Part Context

The 74HC368 belongs to the Nexperia 74HC/HCT series of high-speed CMOS logic devices. It is functionally similar to the 74HC365 but provides inverted outputs instead of non-inverted ones. This family is designed for general-purpose digital applications requiring robust performance across wide voltage ranges and extreme temperatures, commonly found in industrial and consumer electronics.

Replacement Considerations

The 74HC365 can serve as a functional substitute if non-inverting outputs are acceptable. For automotive applications, consider the qualified 74HC366-Q100 or 74HC365-Q100 variants which meet AEC-Q100 standards.
