TECHNICAL DATA
Octal 3-State Inverting
Bus Transceiver
IN74LV640
The 74LV640 is a low-voltage Si-gate CMOS device and is pin and
function compatible with 74HC/HCT640.
The 74LV640 provides six inverting buffers with Schmitt-trigger
action.
• Wide Operating Voltage: 1.2 to 3.6 V
• Optimized for Low Voltage applications: 1.0 to 3.6 V
• Accepts TTL input levels between V_CC =2.7 V and V_CC =3.6 V
• Low input current
