Product Summary

The SN74LVTH125DR is a 3.3-V ABT quadruple BUS buffer. It features independent line drivers with 3-state outputs. Each output is in the high-impedance state when the associated output-enable (OE) input is high. And the bus buffer is designed specifically for low-voltage (3.3-V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment.

Parametrics

SN74LVTH125DR absolute maximum ratings: (1)Supply voltage range, VCC: -0.5 V to 4.6 V; (2)Input voltage range, VI:–0.5 V to 7 V; (3)Voltage range applied to any output in the high-impedance or power-off state, VO:–0.5 V to 7 V; (4)Voltage range applied to any output in the high state, VO: -0.5 to Vcc+0.5 V; (5)Input clamp current: -50 mA; (6)Output clamp current: -50 mA; (7)Package thermal impedance DB package: 96°C/W; (8)Storage temperature range, Tstg:–65°C to 150°C.

Features

SN74LVTH125DR features: (1)Support Mixed-Mode Signal Operation (5-V Input and Output Voltages With 3.3-V VCC); (2)Support Unregulated Battery Operation Down to 2.7 V; (3)Typical VOLP (Output Ground Bounce) <0.8 V at VCC = 3.3 V, TA = 25°C; (4)Ioff and Power-Up 3-State Support Hot Insertion; (5)Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors; (6)Latch-Up Performance Exceeds 500 mA Per JESD 17.
