SN54LS253

The SN54LS253 contains inverters and drivers to supply fully complementary, on-chip, binary decoding data selection to the AND-OR gates. Separate output control inputs are provided for each of the two four-line sections.

The absolute maximum ratings of the SN54LS253 are: (1)Supply voltage, VCC: 7 V; (2)Input voltage, VI: 5.5 V; (3)off-state output voltage: 5.5 V; (4)operating free-air temperature range: -55°C to 125°C; (5)Storage temperature range, Tstg: -65°C to 150°C.

The following is about the electrical characteristics of SN54LS253: (1)VIK: -1.5V max at VCC=min, II=-18mA; (2)VOH: 2.4V min and 3.4V typical at VCC=min, VIH=2V, VIL=max, IOH=max; (3)VOL: 0.25V typical and 0.4V max at VCC=min, VIH=2V, VIL=max; (4)IOZ: 20A max at VCC=max, VIH=2V; (5)II: 0.1mA max at VCC=max, VI=7V; (6)IIH: 20A at VCC=max, VI=2.7V.
