Product Summary

The SN74LVTH244APW is a 3.3V ABT octal buffer/driver with 3-state output. The SN74LVTH244APW 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

SN74LVTH244APW absolute maxing 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 V to VCC + 0.5 V; (5)Current into any output in the low state, IO: 128 mA; (6)Current into any output in the high state, IO: 64 mA; (7)Input clamp current, IIK (VI < 0): -50 mA; (8)Output clamp current, IOK (VO < 0): -50 mA.

Features

SN74LVTH244APW features: (1)Support Mixed-Mode Signal Operation (5-V Input and Output Voltages With 3.3-V VCC); (2)Typical VOLP (Output Ground Bounce)<0.8V at VCC = 3.3V, TA = 25℃; (3)Support Unregulated Battery Operation Down to 2.7 V; (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; (7)ESD Protection Exceeds JESD 22: 2000-V Human-Body Model (A114-A); 200-V Machine Model (A115-A).
