Product details

Overview

74HC368PWJ from Nexperia is a hex inverting 3-state buffer/line driver IC designed for bus interface and signal conditioning in digital systems. It operates across 2.0 V to 6.0 V supply, delivers 19 ns typical propagation delay at 4.5 V, supports -40 °C to +125 °C ambient range, and features TTL-compatible input thresholds in the 74HCT variant. It is used in microcontroller peripheral expansion, memory address/data bus isolation, and industrial control I/O buffering.

For engineers reviewing the 74HC368PWJ datasheet, 74HC368PWJ pinout, 74HC368PWJ application, or 74HC368PWJ equivalent, key selection criteria include its CMOS-level input compatibility (74HC), 3-state output enable timing (15 ns enable/disable), rail-to-rail output swing, low static current (≤160 μA), and TSSOP16 package suitability for high-density PCB layouts.

Technical Context

This device implements six independent inverting buffers, each with active-low 3-state output control via dedicated OE pins (1OE on Pin 1, 2OE on Pin 15). Its logic function follows standard Boolean inversion: when OE is LOW, Y = NOT(A); when OE is HIGH, Y = high-impedance (Z). Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors.

The 74HC368PWJ uses silicon-gate CMOS technology, ensuring high noise immunity (>40% of VCC), latch-up immunity >100 mA per JESD78 Class II Level B, and ESD robustness (HBM >2000 V, CDM >1000 V). It complies fully with JEDEC standards JESD8C (2.7–3.6 V) and JESD7A (2.0–6.0 V).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.0 V to 6.0 V - Enables direct use with 3.3 V and 5 V logic domains without level translation.
Propagation Delay (t_pd)	19 ns max at V_CC = 4.5 V, C_L = 15 pF - Supports reliable operation up to ~25 MHz bus clock rates.

Pinout & Package

TSSOP16 plastic thin shrink small outline package (SOT403-1), 16-pin, 4.4 mm body width, 0.65 mm lead pitch, exposed pad not present. Designed for reflow soldering and high-density surface-mount assembly.

Pin/Terminal	Circuit Role	Design Meaning
1, 15	1OE, 2OE	Active-low output enable inputs - Control groups of three outputs each; HIGH disables all six outputs to high-Z.
2, 4, 6, 10, 12, 14	1A–6A	Inverting data inputs - Each drives corresponding inverted output (1Y–6Y) when respective OE is LOW.
3, 5, 7, 9, 11, 13	1Y–6Y	Inverting 3-state outputs - Assert logical complement of A-input when OE is LOW; float when OE is HIGH.
8	GND	Ground reference - Return path for all internal logic and output currents; must be low-impedance.
16	V_CC	Positive supply - Powers all six buffers; decoupling capacitor (100 nF) required within 1 cm of this pin.

Key Features

Feature	Design Value
Wide supply voltage range	2.0 V to 6.0 V operation enables interoperability across legacy 5 V and modern 3.3 V systems without external regulators.
CMOS input levels (74HC)	VIH ≥ 3.15 V @ VCC = 4.5 V ensures robust noise margin against crosstalk and ground bounce in mixed-signal boards.
Input clamp diodes	Allow safe connection to signals up to VCC + 0.5 V using series resistors - eliminates need for external protection in overvoltage-tolerant interfaces.
High-impedance 3-state outputs	IOZ ≤ ±10 μA @ VCC = 6.0 V guarantees bus contention-free sharing among multiple drivers on common traces.
JEDEC-compliant packaging	SOT403-1 footprint matches industry-standard TSSOP16 land patterns - ensures drop-in compatibility with existing pick-and-place and reflow processes.

Applications

Microcontroller Bus Expansion

Industrial PLC I/O Isolation

Use Scenario: Expanding GPIO count of an ARM Cortex-M4 MCU to drive 16-bit parallel LCD controller and SD card interface simultaneously.

IC Role / Device Role / Timing Role: Inverting 3-state buffer isolates MCU data bus from peripherals; OE pins synchronized to address decode logic to prevent bus contention.

Use Value: Enables time-multiplexed access to two high-capacitance buses using single 16-bit data path, reducing PCB layer count and routing complexity.

Use Scenario: Buffering discrete sensor inputs (limit switches, photoelectric sensors) into a 24 V DC-rated PLC backplane with optocoupler-isolated inputs.

IC Role / Device Role / Timing Role: Signal conditioner translating 5 V logic levels to compatible thresholds for downstream Schmitt-trigger receivers; provides current gain and noise filtering.

Use Value: Eliminates false triggering from EMI in factory-floor environments by raising noise immunity to >1.35 V (VIL) and >3.15 V (VIH) at 4.5 V supply.

Memory Address Latching

Legacy ISA Bus Interface

Use Scenario: Driving 12-bit address lines from a Z80 CPU to dual-port SRAM where address stability must be guaranteed during write cycles.

IC Role / Device Role / Timing Role: Hex inverter with controlled 3-state enables precise timing of address valid window; OE deasserted only during stable address phase.

Use Value: Reduces address setup/hold violations by minimizing propagation skew (<2 ns between channels) and eliminating floating-bus glitches during state transitions.

Use Scenario: Interfacing modern FPGA-based ISA master to legacy ISA peripheral cards requiring strict 5 V TTL-compatible signaling and bus turnaround timing.

IC Role / Device Role / Timing Role: Bidirectional bus driver providing direction control via OE and inversion logic matching ISA's active-low read/write strobes.

Use Value: Meets ISA specification t_dis ≤ 45 ns and t_en ≤ 45 ns at 5 V, enabling compliant 8 MHz synchronous transfers without added glue logic.

Equivalent & Alternatives

The following parts are listed as comparable options for similar hex inverting 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74HCT368PW	TTL-compatible inputs (VIH = 2.0 V min), identical pinout and timing.	Better suited for mixed 5 V TTL/CMOS systems where input drive strength from legacy logic is marginal.	Select when interfacing directly to 74LS or 74F families without level shifters.
SN74LVC1G34DBVR	Single-channel, non-inverting, 1.65–5.5 V supply, SC70-5 package.	Requires six discrete units and external OE logic; lacks native group-enable architecture.	Only viable for ultra-low-power, space-constrained designs where channel independence outweighs board area penalty.

Compared with 74HC368PWJ, the 74HCT368PW offers superior input compatibility with older TTL sources but shares identical thermal, timing, and packaging behavior; the SN74LVC1G34DBVR trades integration and bus-coordination capability for scalability and lower quiescent current per gate.

FAQ

What is the maximum capacitive load the 74HC368PWJ can drive while maintaining specified timing?

The 74HC368PWJ is characterized for 15 pF and 50 pF loads per output in dynamic testing (Table 9). At 4.5 V supply and 15 pF, propagation delay remains ≤19 ns and transition time ≤12 ns. Driving >50 pF increases t_pd nonlinearly and may violate setup/hold margins in synchronous systems - external buffer stages are recommended beyond this limit.

Can 74HC368PWJ be operated at 3.3 V with guaranteed 3-state output leakage?

Yes. IOZ is specified ≤±5.0 μA at -40 °C to +125 °C and VCC = 5.5 V (74HCT), and ≤±10 μA at VCC = 6.0 V (74HC). At 3.3 V, leakage is proportionally lower - typically <±1 μA - well within bus-hold and high-impedance integrity requirements for shared-data applications.

Are the 1OE and 2OE pins internally connected or independent?

1OE (Pin 1) and 2OE (Pin 15) are electrically independent control inputs. 1OE governs outputs 1Y, 2Y, and 3Y; 2OE governs 4Y, 5Y, and 6Y. This dual-OE architecture allows partial bus gating - e.g., disabling only upper or lower byte of a 16-bit bus - without requiring external logic.

Does the 74HC368PWJ require external pull-up or pull-down resistors on unused inputs?

No. Unused inputs should be terminated to VCC or GND to prevent floating nodes that cause increased ICC and potential oscillation. The device does not integrate internal weak pull-ups/pull-downs; however, its high input impedance (II ≤ ±1.0 μA) means 10–100 kΩ external resistors suffice for stable biasing without loading adjacent signals.
