NXP Semiconductors 74HC367N,652

Overview

74HC367N,652 from Nexperia is a hex non-inverting buffer/line driver with 3-state outputs, designed for bus interface and signal isolation in digital systems. It operates across 2.0 V to 6.0 V supply, delivers propagation delay as low as 8 ns at VCC = 6.0 V, supports -40 °C to +125 °C ambient range, and features CMOS-level input compatibility. It is commonly used in microcontroller I/O expansion and memory address/data bus buffering.

For engineers reviewing the 74HC367N,652 datasheet, 74HC367N,652 pinout, 74HC367N,652 application, or 74HC367N,652 equivalent, key selection criteria include 3-state output timing (enable/disable times ≤38 ns), input voltage thresholds (VIH = 4.2 V min at VCC = 6.0 V), thermal rating (-40 °C to +125 °C), and SO16 package compatibility with legacy PCB layouts.

Technical Context

The 74HC367N,652 implements six independent non-inverting buffers, each controlled by one of two active-low output enable inputs (1OE on Pin 1, 2OE on Pin 15). Its CMOS architecture ensures low static current (ICC ≤ 160 μA at VCC = 6.0 V) and high noise immunity, with input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors.

It complies with JEDEC JESD7A (2.0 V–6.0 V) and JESD8C (2.7 V–3.6 V) standards, supports ESD protection per HBM (>2000 V) and CDM (>1000 V), and is rated for latch-up immunity >100 mA per JESD78 Class II Level B - confirming robustness in mixed-voltage industrial environments.

FAQ

What is the maximum operating supply voltage for the 74HC367N,652?

The 74HC367N,652 has an absolute maximum supply voltage (VCC) of +7.0 V, but its recommended operating range is 2.0 V to 6.0 V. Operating continuously above 6.0 V risks parametric drift and reduced reliability; sustained use at 7.0 V violates the Absolute Maximum Rating System per IEC 60134 and may cause permanent damage. For stable long-term operation, maintain VCC ≤ 6.0 V as specified in Table 5 of the Nexperia datasheet.

Does the 74HC367N,652 support hot-swap or live-insertion on a powered bus?

The 74HC367N,652 supports controlled hot-swap via its 3-state outputs: asserting 1OE or 2OE HIGH places associated outputs in high-impedance mode before physical insertion. However, its input clamp diodes require external current-limiting resistors (e.g., 1 kΩ) when connecting to a live bus exceeding VCC, as stated in Section 1. The device itself does not include built-in hot-swap controllers or slew-rate limiting - system-level protection remains the designer's responsibility.

How many independent 3-state control groups does the 74HC367N,652 provide?

The 74HC367N,652 provides two independent 3-state control groups: 1OE (Pin 1) controls outputs 1Y, 2Y, and 3Y (driven by inputs 1A, 2A, 3A), while 2OE (Pin 15) controls outputs 4Y, 5Y, and 6Y (driven by inputs 4A, 5A, 6A). This grouping enables selective bus partitioning - for example, isolating memory address bits A0–A2 from A3–A5 - without requiring additional logic or control lines.

Can the 74HC367N,652 drive a 50 pF capacitive load at 10 MHz without signal integrity issues?

Yes, the 74HC367N,652 is characterized for CL = 50 pF in its dynamic specifications (Table 7): at VCC = 6.0 V, propagation delay is 8–16 ns and transition time is 4–15 ns. With a 10 MHz clock (100 ns period), these values consume <16% of the cycle - well within timing budgets for most synchronous interfaces. Verified performance at 50 pF confirms stable edge integrity and minimal overshoot/ringing when properly decoupled and routed.

Is the 74HC367N,652 pin-compatible with the 74HC367D (SO16) variant?

Yes, the 74HC367N,652 and 74HC367D share identical pin configuration (SOT109-1/SO16), electrical characteristics, and functional behavior per Nexperia's ordering information (Table 1) and pinning diagrams (Fig. 4). Both use the same 16-pin layout with 1OE, 2OE, six A-inputs, six Y-outputs, GND, and VCC in identical positions - enabling drop-in replacement in existing SO16 footprints without PCB modification.
