Product details

Overview

SN74AHC2G34HDCTR from Texas Instruments is a triple non-inverting buffer gate IC operating across 2-V to 5.5-V V_CC, with typical propagation delay of 2.7 ns at 3.0 V/15 pF, ±25-mA output drive capability, and 8-pin DCT (2.95 × 2.80 × 1.1 mm) package. It performs Y = A logic in positive logic and supports industrial temperature range (–40°C to +85°C).

For engineers reviewing the SN74AHC2G34HDCTR datasheet, SN74AHC2G34HDCTR pinout, SN74AHC2G34HDCTR application, or SN74AHC2G34HDCTR equivalent, key selection criteria include supply voltage flexibility (2–5.5 V), rail-to-rail input tolerance (VIH max = 5.5 V), ultra-low quiescent current (1 µA max), and guaranteed switching performance across temperature and load conditions.

Technical Context

This device integrates three independent non-inverting buffer gates in a single monolithic CMOS structure, each implementing Y = A logic with no internal inversion or enable control. All inputs tolerate voltages up to 5.5 V regardless of V_CC level, enabling mixed-voltage interfacing between 3.3-V and 5-V domains.

It operates within –40°C to +85°C ambient temperature, with absolute maximum ratings including V_CC = –0.5 V to 6.0 V and continuous output current up to ±25 mA per channel. Power dissipation is limited to 300 mW in the DCT package at 25°C ambient.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2 V to 5.5 V - supports interoperability across 2.5-V, 3.3-V, and 5-V logic systems
t_PLH/t_PHL (Typ)	2.7 ns @ V_CC = 3.0 V, C_L = 15 pF - enables high-speed signal buffering in compact timing paths
I_O (Max)	±25 mA - drives standard TTL loads and moderate-capacitance PCB traces without external buffers
I_CC (Max)	10 µA @ V_CC = 5.5 V, T_A = 25°C - ensures low static power in battery-backed or always-on subsystems
V_IH(Max)	5.5 V independent of V_CC - allows safe 5-V-tolerant inputs even when V_CC = 2.0 V
Operating Temp	–40°C to +85°C - qualified for industrial-grade embedded control and instrumentation applications
C_pd	8.9 pF @ f = 1 MHz - defines dynamic power consumption during switching activity

FAQ

What logic function does the SN74AHC2G34HDCTR implement?

The SN74AHC2G34HDCTR implements three independent non-inverting buffer functions (Y = A) in positive logic. Each of its three channels passes input logic states unchanged to the corresponding output with no inversion, enable control, or tri-state capability. This makes SN74AHC2G34HDCTR ideal for signal isolation, fan-out enhancement, and voltage-level translation without functional modification.

Does the SN74AHC2G34HDCTR support 5-V-tolerant inputs when powered from 3.3 V?

Yes, the SN74AHC2G34HDCTR supports 5-V-tolerant inputs across its full operating V_CC range (2 V to 5.5 V). Its VIH(max) is specified at 5.5 V regardless of V_CC, allowing direct connection of 5-V signals to any input pin while V_CC = 3.3 V. This eliminates external level-shifting components in mixed-voltage designs involving SN74AHC2G34HDCTR.

What is the maximum output current rating for each buffer in the SN74AHC2G34HDCTR?

Each buffer output in the SN74AHC2G34HDCTR is rated for ±25 mA continuous DC output current (IO) when VO = 0 to V_CC. This specification applies per channel under recommended operating conditions and enables direct driving of LEDs, small relays, and standard TTL loads without additional driver stages. Exceeding ±25 mA risks violating absolute maximum ratings and may impact reliability.

Is the SN74AHC2G34HDCTR suitable for industrial temperature applications?

Yes, the SN74AHC2G34HDCTR is fully characterized and guaranteed for operation from –40°C to +85°C ambient temperature. This industrial-grade qualification is confirmed in the "recommended operating conditions" table of its datasheet and supports use in programmable logic controllers, motor drives, and factory automation equipment where extended thermal stability is required.

What package type and dimensions does the SN74AHC2G34HDCTR use?

The SN74AHC2G34HDCTR uses an 8-pin DCT (thin shrink small-outline) package measuring 2.95 mm × 2.80 mm × 1.1 mm. This surface-mount package features gull-wing leads compatible with standard reflow profiles and is optimized for high-density PCB layouts. The DCT footprint differs from SOIC-8 and requires specific land pattern design per TI's packaging documentation for SN74AHC2G34HDCTR.
