Overview: 74AC125 QUAD BUS BUFFERS (3-STATE) PRELIMINARY DATA s s s s s s s s s HIGH SPEED: tPD = 5 ns (TYP.) at VCC = 5V LOW POWER DISSIPATION: ICC = 8 µA (MAX.) at TA = 25 oC HIGH NOISE IMMUNITY: VNIH = VNIL = 28% VCC (MIN.) 50Ω TRANSMISSION LINE DRIVING CAPABILITY SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 24 mA (MIN) BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 125 IMPROVED LATCH-UP IMMUNITY B M (Plastic Package) (Micro Package) ORDER CODES : 74AC125B 74AC125M equivalent Bipolar Schottky TTL. These devices require the same 3-STATE control input G to be taken high to make the output go in to the high impedance state. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
