NXP Semiconductors N74F367N,602

Overview

N74F367N,602 from Nexperia is a hex non-inverting 3-state buffer/driver IC with dual active-low output enable inputs (OE0, OE1), designed for bus-oriented digital systems. It delivers 5.0 ns typical propagation delay, supports ±64 mA low-level output sink current, and operates at 5 V supply across 0 °C to +70 °C. It is used in address/data bus buffering and bidirectional bus interface applications.

For engineers reviewing the N74F367N,602 datasheet, N74F367N,602 pinout, N74F367N,602 application, or N74F367N,602 equivalent, key selection criteria include 3-state output timing (tPZH/tPLZ ≤ 8.5 ns), input loading (20 µA HIGH/LOW), and DIP16 package compatibility with legacy TTL systems.

Technical Context

The N74F367N,602 implements six independent non-inverting buffers, each controlled by shared active-low output enables OE0 and OE1 - both must be LOW to activate outputs Y0–Y5. Its high-impedance NPN base inputs limit loading to 20 µA in both logic states, enabling direct interfacing with F-series TTL without fan-out degradation.

It features true 3-state outputs with off-state leakage ≤ ±50 µA, supports bus hold-off via high-impedance disable, and meets FAST TTL electrical standards: VIH = 2.0 V min, VIL = 0.8 V max, VOL = 0.55 V max at IOL = 64 mA, and VOH = 2.4 V min at IOH = –15 mA.

FAQ

What is the function of the dual output enable inputs OE0 and OE1 on the N74F367N,602?

The N74F367N,602 uses two active-low output enable inputs (OE0 and OE1) that must both be LOW to activate any of the six 3-state outputs (Y0–Y5). When either OE0 or OE1 is HIGH, all outputs enter high-impedance state. This dual-enable architecture allows coordinated bus control and prevents partial output activation, ensuring clean bus arbitration in multi-master systems. The N74F367N,602 does not support independent enable of subsets of outputs - both enables are globally tied to all Yn pins.

Does the N74F367N,602 support mixed-voltage operation, such as interfacing with 3.3 V logic?

No, the N74F367N,602 is specified strictly for 5 V operation (VCC = 4.5–5.5 V) and TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V). It lacks 3.3 V tolerant inputs or dual-supply capability. Interfacing with 3.3 V systems requires level-shifting circuitry or a logic family bridge. The N74F367N,602 datasheet confirms no characterization or guarantee for operation outside its 5 V commercial range, and applying 3.3 V inputs may result in marginal noise immunity or undefined output behavior.

What is the maximum capacitive load the N74F367N,602 can drive while maintaining specified timing?

The N74F367N,602 AC specifications - including 5.0 ns typical propagation delay and ≤8.5 ns enable/disable times - are characterized at CL = 50 pF with RL = 500 Ω. Driving loads significantly above 50 pF increases propagation delay nonlinearly and may degrade edge rates. For reliable timing compliance, keep total load (including trace capacitance and downstream input capacitance) ≤50 pF. If heavier loads are unavoidable, derate timing margins accordingly or add series termination. The N74F367N,602 does not specify drive capability beyond this test condition.

Is the N74F367N,602 RoHS compliant and lead-free?

Yes, the N74F367N,602 is RoHS compliant and lead-free. Nexperia confirms full compliance with Directive 2011/65/EU (RoHS 2) for this part, including exemption 7a for lead in high-melting-temperature type solders. The DIP16 package (SOT38-4) uses lead-free finish on leads and complies with JEDEC J-STD-020 moisture sensitivity level (MSL) requirements. Full compliance documentation, including material declarations and test reports, is available upon request for the N74F367N,602.

Can the N74F367N,602 be used in place of the obsolete 74F365?

No, the N74F367N,602 cannot substitute for the 74F365. Although both are hex buffers, the 74F365 has inverting outputs (Yn = NOT In), while the N74F367N,602 is strictly non-inverting (Yn = In). Their logic functions are complementary, not interchangeable. The datasheet explicitly states that the 74F365 was discontinued and replaced solely by the 74F367 family for non-inverting applications. Using N74F367N,602 where 74F365 was specified would invert critical control or data signals and cause system failure.
