Product details
Overview
74HC368P-E from Renesas Electronics is a hex bus driver IC with inverted data outputs and 3-state outputs, used for bidirectional data buffering and level translation in digital logic systems. It operates across 2–6 V supply, delivers 9 ns typical propagation delay (CL = 50 pF), supports ±35 mA output current, and features low quiescent ICC of 4 µA max at 25°C - deployed in industrial control backplanes and legacy TTL-to-CMOS interface circuits.
For engineers reviewing the 74HC368P-E datasheet, 74HC368P-E pinout, 74HC368P-E application, or 74HC368P-E equivalent, key selection criteria include its dual active-low enable inputs (G1/G2), inverted output polarity per channel, 3-state output behavior under enable control, and DIP-16 package compatibility with through-hole prototyping and repair workflows.
Technical Context
The 74HC368P-E implements six independent inverting buffer channels, each with separate input (A) and 3-state output (Y), controlled collectively by two active-low enable terminals (G1 and G2). All outputs enter high-impedance state only when both G1 and G2 are asserted low - enabling shared-bus arbitration in multi-driver systems.
Its CMOS design ensures rail-to-rail output swing, VIH/VIL thresholds scale with VCC (e.g., VIH ≥ 4.2 V at VCC = 6 V), and switching characteristics are specified under defined load (CL = 50 pF) and input edge rate (tr/tf ≤ 6 ns), confirming suitability for synchronous 25 MHz bus operation at 4.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0–6.0 V - supports mixed-voltage system interfacing (e.g., 3.3 V logic driving 5 V bus) |
| Propagation Delay (tpd) | 9 ns typ (A→Y, CL = 50 pF, VCC = 4.5 V) - enables reliable timing in 25 MHz synchronous buses |
| Output Drive Strength | ±35 mA per output - sufficient to drive 15 LSTTL loads or terminate short PCB traces |
| Quiescent Supply Current | 4 µA max (Ta = 25°C) - suitable for low-power standby modes in battery-backed systems |
| Input Thresholds | VIH ≥ 4.2 V, VIL ≤ 1.8 V (VCC = 6 V) - provides noise margin >1.2 V in 5 V systems |
| Operating Temperature | –40°C to +85°C - qualified for industrial ambient environments without derating |
| Off-State Output Leakage | ±5.0 µA max (VCC = 6 V) - ensures minimal bus contention during 3-state disable |
Pinout & Package
Dual-in-line plastic package (DIP-16), 2.54 mm pitch, 19.2 mm × 6.3 mm body, through-hole mounting. Pin 1 marked by notch or dot; pin 8 = GND, pin 16 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | G1, G2 (Active-Low Enables) | Both must be low to enable all six outputs; OR logic - allows flexible bus arbitration control |
| 2, 4, 6, 10, 12, 14 | A1–A6 (Data Inputs) | Inverted logic inputs - output Yn = NOT(An) when enabled |
| 3, 5, 7, 11, 13, 16* | Y1–Y6 (3-State Outputs) | Outputs go high-impedance when G1 or G2 is high - prevents bus conflicts |
| 8 | GND | Ground reference for all logic and output stages |
| 16 | VCC | Positive supply rail - powers internal logic and output drivers |
Key Features
| Feature | Design Value |
|---|---|
| Inverted 3-state outputs | Enables bidirectional bus sharing with polarity inversion - eliminates external inverters in address/data latching paths |
| Dual independent enable inputs | Allows hierarchical bus control - e.g., G1 for board-level enable, G2 for subsystem-level gating |
| Wide 2–6 V supply range | Permits direct interface between 3.3 V microcontrollers and 5 V peripheral buses without level shifters |
| Low input current (≤1 µA) | Minimizes loading on upstream logic - critical for fanout-limited clock or control signal distribution |
| High noise immunity | Guaranteed VIH/VIL margins exceed 30% of VCC across full voltage range - resists EMI in industrial enclosures |
Applications
| Industrial Backplane Interface | Legacy System Bus Extender |
|---|---|
Use Scenario: Interfacing a modern 3.3 V FPGA I/O bank to a legacy 5 V ISA-style backplane with shared data/address lines. IC Role / Device Role / Timing Role: Inverting 3-state bus driver - translates logic levels while providing bus contention protection via dual-enable control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverting bus driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC368N | Identical logic function and pinout; TI version rated for same VCC (2–6 V) and Ta (–40°C to +85°C); tpd = 10 ns typ (CL = 50 pF) | No functional deviation - validated in identical industrial backplane designs | Select when requiring TI's long-term availability program or dual-sourcing strategy |
| 74HCT368N | TTL-compatible input thresholds (VIH = 2.0 V min); otherwise identical pinout and 3-state behavior; tpd = 11 ns typ | Better interoperability with 5 V TTL outputs without level shifting; not recommended for 3.3 V-only systems | Choose for mixed 5 V TTL/CMOS systems where input noise immunity from legacy drivers is critical |
Compared with SN74HC368N and 74HCT368N, the 74HC368P-E offers identical pinout and core functionality but is optimized for Renesas' industrial qualification flow and DIP-16 packaging - making it preferred for repair, legacy replacement, and applications requiring Renesas-specific traceability and documentation support.

FAQ
What is the logic function of the 74HC368P-E?
The 74HC368P-E is a hex inverting bus driver with 3-state outputs. Each of its six channels accepts a true logic input (A) and produces an inverted output (Y) when both enable inputs (G1 and G2) are low. When either G1 or G2 is high, the corresponding Y output enters high-impedance state - allowing multiple 74HC368P-E devices to share a common bus without contention.
Does the 74HC368P-E support 3.3 V operation?
Yes, the 74HC368P-E supports 3.3 V operation within its specified 2.0–6.0 V supply range. At VCC = 3.3 V, VIH is guaranteed ≥ 2.31 V and VIL ≤ 1.09 V, providing adequate noise margin for clean interfacing with 3.3 V microcontrollers and FPGAs - confirmed in Renesas' Recommended Operating Conditions table.
What is the maximum output current rating for the 74HC368P-E?
The 74HC368P-E has a maximum output current rating of ±35 mA per output terminal, as specified in the Absolute Maximum Ratings table. This value applies under steady-state DC conditions and enables direct driving of 15 LSTTL loads or termination of short PCB traces - consistent across the full –40°C to +85°C operating temperature range.
How are the enable inputs G1 and G2 configured in the 74HC368P-E?
The 74HC368P-E uses two active-low enable inputs, G1 (pin 1) and G2 (pin 15), wired in logical AND configuration: all six outputs are enabled only when both G1 and G2 are low. If either input is high, all outputs go to high-impedance - a design that supports hierarchical bus control and fault-isolation schemes in multi-board systems.
Is the 74HC368P-E RoHS compliant?
Yes, the 74HC368P-E is RoHS compliant. Renesas Electronics confirms environmental compliance in accordance with EU Directive 2011/65/EU (RoHS 2), including restriction of lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE. The device uses Ni/Pd/Au plating on leads and meets JEDEC standard J-STD-020 moisture sensitivity level (MSL) requirements for DIP-16 packaging.
